Abstract
The operation of a two-level gas laser in schemes with single-sided and double-sided transverse diode pumping is investigated theoretically. If the reflection coefficient of the output mirror is not too small, analytical formulas are obtained that describe the operation of a two-level gas laser with single-sided and double-sided diode pumping and make it possible to determine any laser energy characteristics and to find optimal parameters of the working medium and pump radiation that are required for the most effective laser operation. It is shown that the generation efficiency of a two-level gas laser can be increased by 11-20% when switching from single-sided to double-sided pumping.
