Continuous lasing in F/sub 2//sup -/ centers in a crystal of LiF was observed in the 1.14--1.2 ..mu.. range. At room temperature the output power was 70 mW when the crystal was pumped with a cw YAG:Nd/sup 3 +/ laser (lambda = 1.06 ..mu..) of 9 W power. The possibility of increasing the efficiency of the color-center laser was analyzed. At a high pulse repetition frequency the average output power was 120 mW. In this case a Q-switched YAG:Nd/sup 3 +/ laser was employed (the pulse repetition frequency was 50 kHz, the pulse duration was 1 ..mu..sec, and the pump pulse power was 70 W). The Q factor was modulated by a passive switch whose operation also depended on F/sub 2//sup -/ centers in an LiF crystal.
