The main goal of research is the maximal extension of the range of technical parameters of existing metal vapor lasers due to the use of new laser media and the efficient frequency conversion of laser radiation in nonlinear crystals, organic dyes, and other media.
The cycle of theoretical and experimental studies has shown that minor additions of H2, HCl, and HBr to active media of copper vapor and copper bromide vapor lasers significantly improve their output parameters mostly due to the decrease of the prepulse electron concentration. The results obtained have formed the basis for the development of sealed-off active elements of copper bromide vapor lasers with a built-in HBr generator.
A new generation of lasers: metal halide vapor lasers with an active thermal insulator operating in the train mode (standby mode is an important particular case) controlled by an external program. The use of the active thermal insulator has allowed the longitudinal capacitive discharge to be applied for the first time for the pumping of self-terminating metal vapor lasers. The possibility of using this pumping in compact sealed-off metal halide vapor lasers has been demonstrated.
