Suppression of spatial hole-burning in a standing wave solid-state laser with a degenerate resonator

ORAL

Abstract

We numerically and experimentally demonstrated that the spatial hole burning in a solid-state laser with a standing wave resonator can be suppressed in use of a tightly-focused pumping beam. The laser can self- adjust its mode waist to match the small pump volume when it is operated in a degenerate cavity configuration, so that variation of the gain profile along the laser crystal can be minimized via the gain saturation.
