Abstract
A search for new laser transitions is carried out in the spectrum of Sr II by using a mathematical model of the He-Sr recombination laser. The calculations revealed that under strongly non-stationary conditions it is possible to obtain a population inversion and lasing at the leading edge of the recombination pumping pulse on the ultra-violet transitions 52D3/2,5/2→52P1/2,3/2Sr II (λ = 338.1 and 346.4 nm). In this regime, the inversion arises as a result of transient processes at the establishing of populations of laser levels and it exists several nanoseconds, similar to that of self-terminated lasers.
