Theoretical research of a potassium diode-pumped alkali laser

The results of computational and theoretical studies of diode-pumped alkali laser parameters are presented. A mathematical model of the pumped alkali laser is constructed, a numerical solution of the equations of kinetics and laser radiation transfer considering the width of the pumping spectrum is given, and the optimal parameters of the laser installation were obtained, at which the calculated “light-to-light” efficiency is more than $50 \%$.
