The experimental and numerical studies on optimization of parameters of small-scale ion recombination He Sr lasers (l = 430.5 nm SrII) are carried out. In particular, the detailed analysis of the factors, which help to achieve the high output power characteristics is carried out. The experimental optimization of the small-scale He Sr laser at cataphoretic entering of strontium vapor into active medium is carried out. The maximum values of the specific output average power, laser pulse repetition rate and gain on λ = 430.5 nm SrII line were achieved. With the help of the self-consistent mathematical model of the He Sr laser the numerical experiments on optimization of active elements of the various geometric sizes are carried out. The good agreement of results of modeling with experimental data is obtained. On the base of these studies the attainable frequency-output power characteristics of the laser oscillations are determined. The possibility is demonstrated for a pulse repetition rate and specific output average power significant increase compared to values, previously reached in experiments. A number of tendencies is established, which are helpful for a meaningful selection of design of the small-scale active elements and optimal excitation conditions.
