Solid-state lasers with self-pumped phase-conjugate mirrors in an active medium

Abstract

Lasing was observed in a system with self-pumped "loop" phase-conjugate mirrors in YAG:Nd3+, KGW:Nd3+, and GSGG:Cr3+:Nd3+ active media. An investigation was made of the threshold, energy, spectral, and temporal characteristics of the output radiation under lasing and regenerative conditions.
