Experimental optimization of self-heated He-Sr+(Ca+) recombination lasers of different geometries is carried out. Regularities and tendencies in the behavior of the discharge excitation parameters and output characteristics are revealed. The physical processes determining these regularities are established. The capability of fast variation of output laser characteristics with the help of additional controlling current pulses formed in the discharge near afterglow is demonstrated. The dependences of output characteristics on characteristics of controlling pulses are calculated with the help of the mathematical modeling.
