ABSTRACT: 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 CO2-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.
