“…Only the nearest future will show the details of physical-technical solution for the best laser which will be used effectively for many important challenges faced by science and technological advances of the future. However, today we can say that creation of high power class high frequency P-P lasers with a large cross section of the active medium, high compactness and low weight will open up a great prospect for their use in solving the problems of launching of small satellites by lasers, formation of super-long conducting channels in space for wireless power transmission (vacuum and atmosphere), cleaning of the near-Earth space from debris and many other special tasks of our days [32] [33].…”

For many years the attempts to create a super long conductive channel were taken in order to study the upper atmosphere and to settle special tasks, related to the energy transmission. There upon the program of "Impulsar" creation represents a great interest, as this program in a combination with high-voltage high repetition rate electrical source can be useful to solve the above mentioned problems. It looks like as some kind of "renaissance of N. Tesla ideas" for the days of high power lasers. In the experiments the GDL CO 2-laser and solid state Nd YAG laser systems had been used. Theoretical and experimental investigation of high repetition rate P-P mode of operation for high power lasers (COIL, HF/DF) had been provided. The experimental realization of P-P regime has been demonstrated for 100 KW GDL and 1 kW LD pumped SSL. More than two orders of magnitude ratio of peak to average power with minimal energy loss have been obtained. High efficiency and excellent beam quality of disk laser mean that it can be widely used in modern science and industry. Disk laser idea, suggested by N. G. Basov 52 years ago, after implementation in the mono-module disk geometry can be used effectively for many important challenges faced by science and technological advances of the future. Today we can say that creation of megawatt class mono-module P-P disk laser with a large cross section of the active medium opens up great prospects for its use for solving of the set of problems: small satellites launching by lasers, formation of super-long conducting channels in space (vacuum and atmosphere), cleaning of the near-Earth space from the debris and so on.

“…Thus, a bulky silicon carbide mirror has a weight that is 5-7 times less than the weight of a similar mirror made of glassceramic, the best quality in terms of surface scattering, high thermal stability and a minimum time constant when changing the external temperature. Obviously, the transition to a new generation of space-based telescopes, high-power large mirrors of high-power lasers is not possible without the introduction of silicon carbide in practice [57][58][59][60][61][62][63].…”

The advent of the laser has placed stringent requirements on the fabrication, performance and quality of optical elements employed within systems for most practical applications. Their high power performance is generally governed by three distinct steps, firstly the absorption of incident optical radiation (governed primarily by various absorption mechanisms); secondly, followed by a temperature increase and response governed primarily by thermal properties and finally the elements thermo-optical and thermomechanical response, e.g., distortion, stress birefringenous fracture, etc. All of which needs to be understood in the design as efficient, compact, reliable and useful for many applications high power systems, under a variety of operating conditions, pulsed and continuous wave, rep-rated or burst mode of varying duty cycles.
