Abstract: The influence of pump geometry on the generation efficiency of a transversely diode-pumped alkali metal vapour laser is studied theoretically. Analytical formulas describing the operation of a high-intensity laser with double-sided diode pumping in two orthogonal directions are obtained. It is shown that the generation efficiency of an alkali metal vapour laser can be increased by 8% – 18% when switching from single-sided to double-sided pumping.

Keywords: alkali metal vapour laser, diode pumping, atomic collisions.
