    It is all just further proof that the human race is a failed experiment... a doomsday bomb is the solution... or a good world wide plague that will kill 6 billion people perhaps...

It would make practical sense that a nuclear powered laser would also be a nuclear-pump-laser as well. It was confirmed the power was 1MW (like what I speculated) which leads me to believe that it is indeed Peresvet.

    In 2012, the source [1] reported that in the RFNC-VNIITF (Snezhinsk) a gas laser pumped by a nuclear reactor operating at the atomic xenon transition with a wavelength of 2.03 μm was created. The output energy of the laser pulse was 500 J at a peak power of 1.3 MW. This device is the most compact in terms of the volume of active gas medium used (specific laser radiation energy was 32 J / dm³)

    https://translate.yandex.com/translate?url=https%3A%2F%2Fru.wikipedia.org%2Fwiki%2F%D0%9B%D0%B0%D0%B7%D0%B5%D1%80_%D1%81_%D1%8F%D0%B4%D0%B5%D1%80%D0%BD%D0%BE%D0%B9_%D0%BD%D0%B0%D0%BA%D0%B0%D1%87%D0%BA%D0%BE%D0%B9&lang=ru-en

    A 520 J pulsed gas laser (laser module) was created, pumped by fission products of uranium nuclei, operating at the atomic transition of xenon 5d [3/2] 1 -> 6p [3/2] 1 , with a wavelength of 2.03 mum. The experiments were carried out on the BARS-5 + RUN-2 complex (Fast aperiodic self-quenching reactor and Reactor neutron multiplier). The specific energy of laser radiation obtained in the experiments was ~ 32 J / dm 3 at an efficiency of ~ 3% (the ratio of the output energy of the laser pulse to the energy transferred to the gas medium by fission fragments).

    Some wild guesses here. But Im guessing one of the reasons why Peresvet's program got greenlighted is because the laser is boosted with other forms of electromagnetic radiation, including microwaves and gamma radiation, which might allow it to perform the duties of DEW and ECM all in one package. So theoretically speaking Peresvet may actually be both a Laser and a Maser.

    More on nuclear-pump lasers:


     

    Nuclear-pumped lasers






    Since the late 1960s, work began on the creation of high-power nuclear-pumped lasers in the USSR. Initially, the specialists of VNIIEF, IAE im. Kurchatov and Research Institute of Nuclear Physics, Moscow State University. Then scientists of MEPhI, ¬VNIITF, IPPE and other centers joined them. In 1972, the VNIIEF excited a mixture of helium and xenon with uranium fission fragments using the VIR 2 pulsed reactor

    . experiments are being conducted at the TIBR-1M reactor, in which the laser radiation power was about 1-2 kW. In 1975, on the basis of the VIR-2 pulsed reactor, a two-channel laser unit LUNA-2 was developed, which in 2005 still worked, and it is possible that it still works. In 1985, a neon laser was pumped for the first time in the world at the LUNA-2M installation.

    LUNA-2M installation


    In the early 1980s, VNIIEF scientists, to create a nuclear-laser element operating in continuous mode, developed and manufactured a 4-channel laser module LM-4. The system is excited by a neutron flux from the BIGR reactor. The duration of the generation is determined by the duration of the irradiation pulse of the reactor. For the first time in the world, continuous generation in nuclear-pumped lasers was demonstrated in practice and the efficiency of the transverse gas pumping method was demonstrated. The laser power was about 100 watts.



    Peresvet laser complex - Page 8 1580459230_07-lm-4
    Installation LM-4


    In 2001, the LM-4 installation was modernized, receiving the designation LM-4M / BIGR. The operation of a multi-element nuclear laser device in continuous mode was demonstrated after 7 years of preservation of the installation without replacing optical and fuel cells. The LM-4 installation can be considered as a prototype reactor-laser (RL), possessing all its qualities, except for the possibility of a self-sustaining nuclear chain reaction.

    In 2007, instead of the LM-4 module, the eight-channel laser module LM-8 was put into operation, which provided for the sequential addition of four and two laser channels.



    Peresvet laser complex - Page 8 1580459264_08-lm-8
    Installation LM-8


    The laser reactor is an autonomous device that combines the functions of a laser system and a nuclear reactor. The active zone of a laser reactor is a set of a certain number of laser cells placed in a certain way in a neutron moderator matrix. The number of laser cells can range from hundreds to several thousand pieces. The total amount of uranium is from 5-7 kg to 40-70 kg, linear dimensions 2-5 m.

    VNIIEF carried out preliminary assessments of the main energy, nuclear-physical, technical and operational parameters of various versions of laser reactors with a laser radiation power of 100 kW and above, operating from fractions of a second to continuous operation. Reactor lasers with heat storage in the reactor core at start-ups, the duration of which is limited by the permissible heating of the AZ (heat-capacitive radar) and continuous radar with the removal of thermal energy outside the AZ



    Peresvet laser complex - Page 8 1580459269_09-reaktor-lazer
    Heat capacitive radar and continuous radar


    Presumably, a laser reactor with a laser power of about 1 MW should contain about 3,000 laser cells.

    In Russia, intensive work on nuclear-pumped lasers was carried out not only at VNIIEF, but also at the Federal State Unitary Enterprise State Scientific Center of the Russian Federation - A.I. Leipunsky ”, as evidenced by patent RU 2502140 for the creation of a“ laser-laser reactor with direct pumping of fission fragments. "

    Specialists of the SSC RF IPPE developed an energy prototype of a pulsed reactor-laser system - an optical nuclear-pumped quantum amplifier (OKUYAN).

    OKUYAN based on the BARS-6 reactor


    Remembering the statement of the Deputy Minister of Defense of Russia Yuri Borisov in the last year’s interview with the Krasnaya Zvezda newspaper (“We received laser systems that make it possible to disarm a potential enemy and hit all those objects that serve as the target for the laser beam of this system. Our nuclear scientists learned how to concentrate energy necessary to engage the respective arms of the enemy virtually instant, in a matter of seconds ") , we can say that the BLK" Relight "not equipped with small c Chassis Basic nuclear reactor, power supply laser, a laser reactor in which fission energy is directly converted into laser radiation.

    Only the aforementioned proposal makes it possible to place Peresvet BLK on an airplane. No matter how you ensure the reliability of the carrier aircraft, there is always a risk of an accident and a plane crash with the subsequent spread of radioactive materials. However, it is possible that there are ways to prevent the spread of radioactive materials when the carrier falls. And the flying petrel in a cruise missile cruise missile we already seem to have.

    Based on the foregoing, it can be assumed that the probability of the implementation of the Peresvet BLK in version 3 based on a nuclear-pumped laser can be estimated as high.

    It is not known whether the installed laser is pulsed or continuous. In the second case, the time of continuous operation of the laser and the breaks that must be carried out between the operating modes are in question. I would like to hope that a continuous laser reactor is installed in the Peresvet BLK, the operating time of which is limited only by the supply of refrigerant, or not limited if the cooling is provided in any other way.

    In this case, the output optical power of Peresvet BLK can be estimated in the range of 1-3 MW with the prospect of increasing to 5-10 MW. It is hardly possible to hit a nuclear warhead even with such a laser, and a plane, including an unmanned aerial vehicle, or a cruise missile, is completely. It is also possible to ensure the defeat of virtually any unprotected spacecraft in low orbits, and it is possible to damage sensitive elements of spacecraft and higher orbits.

    Thus, the first goal for Peresvet BLK may be the sensitive optical elements of the US missile attack warning satellites, which can act as an element of missile defense in the event of a US disruptive strike .


    conclusions




    As we said at the beginning of the article, there are a fairly large number of ways to obtain laser radiation. In addition to the ones discussed above, there are other types of lasers that can be effectively used in military affairs, for example, a free-electron laser, in which it is possible to widely vary the wavelength up to soft x-ray radiation and which just needs a lot of electric energy produced by small-sized nuclear reactor. Such a laser is being actively developed in the interests of the US Navy. However, the use of a free electron laser in Peresvet BLK is unlikely, because at present there is practically no information on the development of such lasers in Russia, apart from participation in Russia in the European free electron x-ray program.

    It must be understood that the assessment of the probability of applying one or another solution to the Peresvet BLK is given conditionally: the presence of only indirect information obtained from open sources does not allow us to draw conclusions with a high degree of reliability.

    It is possible that the conclusion about the high probability that the Peresvet BLK uses a laser with a nuclear pump is partially made not only on the basis of objective factors, but also on the underlying desire of the author. For if Russia really created a laser with a nuclear pumping power of megawatts or more, this opens up extremely interesting prospects for creating weapons systems that can radically change the face of the battlefield. But we will talk about this in another article.

    PS In order to eliminate questions and disputes about the influence of the atmosphere and weather on the operation of lasers, it is highly recommended to study the book by A. S. Boreisho, “Powerful Mobile Chemical Lasers,” at least Chapter 6, entitled “Propagation of Laser Radiation at Operational Distances”.

    ...So Peresvet may have a power output of 1-3 MW, with a potentially increase up to 10 MW output.

    God magnum the translation is driving me nuts. Like that it is hardly possible to hit a nuclear warhead, plane, uav and cruise missile than after listing all that it says is completely.


    Any fluent russian speaker here? I cant tell
    if they saying it is barely possible or it is saying it is completely possible to destroy those targets.

    Machine translation is always wonky....they're saying with enough power (say 10 MW) and with the right circumstances (like a flying platform at high altitude) it could potentially defeat them. Gorby the betrayer cancelled a space based program while the Yanks had Star Wars ongoing, which goes to show the guy with the bird poop birth mark was such a spineless loser. As Mindstorm has brought up, higher altitude (or even space based) laser platforms are completely different animal than land based laser platforms.

    A free-electron laser is an oxymoron. No charged particle beam can maintain any coherence since electric repulsion is huge
    and long range. Photons avoid this issue and do not have any upper bound on the density that can be produced and lased. Of course,
    at some stage the laser will simply evapourate if the photon density is too high. But even packing free electrons into a small volume
    is extremely self-limiting.

    It is rather clear that there have been several nuclear reactor advances in Russia that have given us Burevestnik and Peresvet.
    Some experiments from the 1960s are not a useful guide as to what sort of technology we are dealing with today. That is top
    secret and not a trivial variation of 1960s tech.

    The article chokes on the idea of flying a nuclear driven laser on a plane because of potential contamination during an accident.
    This is an example of small-think. During WWIII nobody will care about any contamination since there will be plenty of it coming
    from all the mushroom clouds. So if putting a nuclear laser in flight can save a city from being glassed, then no second thought
    will be given about deploying such a system. It is really simple cost vs. benefit analysis. Also, contaminated crash sites can be
    cleaned up. So all reservations and concerns about reactors crashing is just so much anti-nuclear hysteria.

    It is evident that the Peresvet system can be mounted on a jet. It is unlikely to weigh more than 30 tons. We also do not know
    if the current Peresvet reactor is the final variant. Burevestnik makes me think that some substantial progress has occurred in
    downsizing of reactors.

    It's interesting how people freak out about anything nuclear. People are afraid of nuclear material contaminating if there's a crash, but their not worried about a +100 ton aircraft full of kerosene crashing and causing a massive forest fire, which under the right conditions uncontrolled fires give you whats going on right now in Australia.

    The kerosene combustion products from a crash fire are full of carcinogens, mutagens and teratogens thanks to poor combustion.
    Human sheep think that chemicals are safer than radioactive substances. BS. There is no rule that makes radiation more dangerous
    than disruptive organic chemistry. There is dose dependence and radioactive compounds have half lives. By contrast, nasty organic
    chemicals can keep on being nasty even as they are oxidized with daughter products being no less damaging to health than the precursor.
    Conversion to CO2 and H2O takes a freaking long time and there are thousands of generations of thousands of daughter products from
    a single compound.

    BTW, firefighters have some of the highest death rates from cancer. Nuclear plant workers do not show any increased risk compared
    to the general population.

    Apparently Peresvet isn't just a means of attack, but also a means of detection. Apparently it was originally filed as a patent for a 'mobile optical telescope.'

    From Cyberspec's twitter:

    "CO2 pulse laser with 420 mm germanium windows...not much known about this, but most likely leaked pic of an older project"
    Peresvet laser complex - Page 8 EU-CtQqUcAETDjA?format=jpg&name=medium

    https://twitter.com/Cyberspec1/status/1247359628381323264

    Probably something from the period of late 80's-2000's. I can see Peresvet being placed on it's vehicle chassis to increase mobility.

    Also a friendly reminder on Peresvet is (I posted this in another thread): Peresvet is likely a hybrid DEW/ECM, a Laser/Maser/Graser combination to not just melt/burn munitions with a intense pencil beam Laser, and with the Maser (focused microwaves) and Graser (focused gamma radiation beam) to fry the electronics by inducing high current electromagnetic electrostatic discharge, like a direct beam EMP.
