Results of experimental research of frequency and energy characteristics of laser on self-terminating transitions in strontium ion (λ = 1.03 and 1.09 µm) by the method of introduction of an additional pulse before each excitation pulse and the results of theoretical calculations of parameters of Не-Sг+ laser active medium are presented. It is shown, that pulse repetition rate of self-terminating Не-Sг+ laser can reach ~ 1 MHz and the increase of pulse energy in a certain pulse-delay range is thus observed.
