Optimal scaling of He — Sr+(Ca+) recombination lasers

A method for scaling optimal parameters of the discharge-heated He — Sr⁺(Ca⁺) recombination lasers is suggested. The method can be used for calculating the optimal excitation parameters and output characteristics of laser tubes of arbitrary dimensions from the known parameters of the optimised laser tube. The experimental verification of the scaling relations showed reasonable agreement between calculations and the experimental data, which is acceptable for practical applications.
