Controlling the characteristics of strontium and calcium vapor recombination lasers
Incoming article date: 21.11.2017Possible methods of high-speed control of the output characteristics of recombination He-Sr and He-Ca lasers using mathematical models are analyzed. The capability is demonstrated of wide-range control of laser output characteristics with the help of two methods – by varying the amplitude of the additional current pulse imposed on early afterglow of the pulse-periodic discharge and by varying the moment of this pulse imposing. The dependences of the laser output characteristics on the parameters of the additional current pulses are numerically calculated. The mechanism of their influence on the population of laser levels is established. The results obtained make it possible to purposefully form control current pulses for the recombination metal vapor lasers.
