III. A dding M odules does not L ead to P rogress Here it is necessary to dwell in more detail on the already created ss disk laser technology. This idea of the academician Basov is already 55 years old, but it is his principle of building powerful LC that is dominating today and in the future. With the same very advantageous factor of less than 5 kg / kW as for fiber technology, this design principle allows the implementation of a high-energy high-frequency pulse- periodic (P-P) mode, so as the aperture of the disk laser that exists today with a diameter of about 1.5 centimeters, which is much larger than the diameter of the active body of the fiber laser. To increase the average power of the system, several disks are added in an optical sequence ZIG-ZAG, the average power of such a module today is already 50 kilowatts. Modules, as in the case of fiber systems, can be built in parallel and the power is added to the target. Based on the above figures, it can be seen that a one-hundred- kilowatt laser will weigh less than 500 kilograms! The spectral addition of the modules ' radiation leads to an increase in the pulse energy in a high-frequency periodic sequence, which qualitatively changes the interaction mechanism. However, it should be noted that to perform the tasks. The Armed Forces of the Russian Federation need LW complexes of much greater average power. Fiber laser technology is limited to the tactical level of medium power, and created in the United States with the help of the complex with a power of 300 kilowatts of spectral addition has convincingly proved this. At the same time, the disk technology that exists today, even with a module of 75 kilowatts (Lockheed Martin plans to increase this due to the quality of reflective coatings), will reach the power level of the entire system of about 10 megawatts, whether he can. It is impossible to combine the power of more than a hundred modules into a single beam of a mobile complex. It is appropriate to recall the well-known in the history of solid-state laser creativity experimental models of complexes created in the USSR, "Omega" (96 modules) and "Tandem" (60 modules) from the point of view of the feasibility of their tactical and technical parameters and reliability. It is obvious that a different constructive construction of the ss LW complex is necessary, which would allow further effective scaling of its average power while maintaining the minimum weight factor characteristic of a modern solid-state LW. IV. A rrow and S hield D ispute In the article "Laser spears for the defense of Russia" /2/ the discussion of the proposed new approach to the creation of a ss monomodule disk laser with a large diameter of the working fluid has begun. The article aroused great interest among laser specialists in the country, a series of meetings has already been held with a detailed discussion of the new opportunities provided by the developed technology of advanced laser systems. Emerging technologies pose new questions to the developers of defeat systems, and this in turn calls to life the improvement of already created technologies. Which once again poses difficult challenges for the creators of weapons. Such a step in solving the problems of destruction is the creation of a scalable laser source with a monomodular disk geometry, which solves two problems inherited from Academician Basov: the effective cooling of the body of a large-diameter disk and the suppression of the amplification of spontaneous emission (ASE) along its diameter. So, it is clear that mobile LW can be obtained only on the basis of new technical and technological solutions. But strategic. There is no law yet, and in the near future a way out of the ideological impasse can only be found based on ss technology. The entire scientific world is in search of this constructive basis. We have the idea of creating it, it is analyzed in detail, numerically modeled, tested on models and is waiting for its implementation. On this basis, the entire line of light and compact LW can be obtained from hundreds of watts to many tens of megawatts. Let me remind you that in the US, by the end of 2022, the aircraft will be equipped with a tactical LW. At significant altitudes, where MANPADS do not reach the aircraft carrier, there is no large scattering and absorption, and the range of destruction for the LW with a capacity of 100-150 kilowatts, they increase to several tens of kilometers in power mode (violation of the integrity of the structure). In functional mode (in the US, this mode is called "smart interaction») the distance of the lesion increases significantly, but there is no complete certainty about the reality of the effect of the lesion. Further. On the basis of fiber lasers with the spectral addition of radiation from single sources in the United States, LW complexes with an average power of 30, 60, 100 kilowatts have been consistently created. The weight of the complex based on a fiber laser is brought to the level of 5 kg / kW. It is shown that with further scaling, the TTK can be reduced to 2 kg / kW, in the US, the development of an already created prototype of a laser system of 300 kilowatts and a total weight of only 600 kilograms is underway. The illusory nature of further increasing the power of such a LW in the chosen design is convincingly shown. Obviously, we need a different scheme of the ss LW complex, which allows us to would further scale its average power while maintaining the achieved weight factor. This is particularly important when equipping spacecraft with lasers, a similar task is already on the agenda in the US.
