against hypersonic missiles) and the accumulated experience of operating already created LW on an outdated physical and technical basis, the need for creating complexes is confirmed. A LW with an output power of several tens of megawatts. A partial return to the SDI program has already been announced by the US Joint Chiefs of Staff. High-energy fiber lasers, due to physical limitations, cannot be high-frequency P-P at a large average output power due to the destruction of the fiber. The spectral composition of the radiation of these compact and light LW complexes, even in the continuous generation mode, is limited by the tactical level of average power. This is the whole limitation of fiber technology, not only the strategic level of power, but also many new exposure modes and effective applications of high-frequency P-P radiation from high- energy lasers is impossible for them. The existing world-wide ss laser technology based on disk geometry, developed by Academician Basov at the FIAN, as well as fiber laser technology, does not allow us to solve the problem of further scaling the average power of LW complexes to strategic characteristics. The only promising and effective at the moment constructive approach to the creation of the entire line of ss LW complexes from the tactical to the strategic levels is the monomodule technology proposed in Russia (GPI RAS). It is obvious that the new aviation complex LW SHiELD created by the Americans will not only be able to defend against a missile attack, but will also become a serious threat to the objects of military equipment (OME) and enemy aircraft. Laser radiation is significantly absorbed and scattered in the desert conditions in the Middle East, where they conducted tests of tactical LW systems to combat drones. It is known that under these conditions, the beam power drops three times at every mile of the distance. And this really complicates the use of LW in conditions of high dust and humidity. But none of this is true. It follows the conclusion of some experts that the law is ineffective in principle. It is necessary to increase the capacity of the complexes and create a higher level of average power, go to other time modes of generated radiation. There are other military tasks besides destroying drones. This is the use of LW in the upper atmosphere and in space. At altitudes of seven to nine kilometers, the environment is more transparent and the target ranges for destroying OME even for a power level of 100-150 kilowatts can be many tens of kilometers. And if we are talking about the megawatt level, then it is already historical works experts from the USA and the USSR experimentally proved the reality of the range of active operation of "laser monsters" in 100 kilometers. Another thing is that all this is again a tactical range and it is necessary to continue to increase the average power of the LW to achieve a strategic level of range 1000 or more kilometers with a significant reduction in their weight and size. It is already clear that the chemical, gas, and metal vapour-based LW, with their enormous size, have left this strategic road. Now among scientists and designers, understanding dominates the fact that only the solid-state basis of the active element of the LW complex, fiber and disk geometries determine the future of the LW for almost all branches of the armed forces. The question of the range of destruction of OME in space will rest only on the optical quality of the generated radiation. But apart from the quality of the beam, there is another problem – the multi-megawatt LW complex must be put into space. For this purpose, in the US, the emphasis is on creating a solid-state technology that allows you to provide a weight factor of 2 kg/kW and even lower. And there are still great difficulties here. V. T here is a S olution, B ut… A few words about the problem of protection from laser radiation. Yes, on the football field, the goalkeeper can easily cover himself with a glove from an annoying fan with a laser pointer. But with a laser power 30 kilowatts this trick will not pass. Drones in the Middle Eastern sky were burning at a distance of 1.5-2 kilometers. But these were toys in comparison with modern multi-ton drones made of titanium and aluminum alloys. Here, even 100 kilowatts of continuous radiation at tactical distances in the power mode of destruction may not be enough. But in the functional high-frequency I-P mode, it will be more than enough. This is a mode in which the laser energy is released as a sequence of short pulses with a high repetition rate. At the same time, the peak power of individual pulses is hundreds or thousands of times higher than the average power of the same LW in the normal continuous generation mode. Leading experts in the field of creating high-power high-frequency P-P lasers and the authors of the patent they are employees of the GPI RAS, who worked under the leadership of Academician Prokhorov. The same team proposed and experimentally tested a laser engine based on the mechanism of a high- frequency optical pulsating discharge and obtained record-breaking characteristics of the engine thrust. Using a high-frequency IPP laser, an intense and frequency-varying sound in the far zone is obtained, containing up to 20 % of the laser energy, a conducting channel with a minimum resistivity is experimentally implemented, the possibility of its scaling to significant distances and the reality of such a highly conducting channel, including in a vacuum, are shown. These new- old technologies-P-P mode with a high pulse repetition rate (more than 10 kHz) and a monomodule disk-are perfectly combined in a single laser complex. In particular, we, in addition to the experimental demonstration of the mode at level 10 kilowatts and cutting of metals, glass and composites, theoretically shown to be highly effective for the destruction of space Laser without a Moscow Residence Permit 1 Year 2022 9 © 2022 Global Journals Global Journal of Science Frontier Research Volume XXII Issue ersion I VI ( A )
