EFFICIENT TUNABLE LiF:F2 - CRYSTAL LASERS.

Academic Article

Abstract

  • Optimization of the technology of preparation of active elements made of LiF crystals containing F//2** minus color centers ensured high values of the parameters of wide-band generation of light by the F//2** minus color centers in a nonselective resonator pumped with YAG:Nd**3** plus laser radiation. The efficiency measured relative to the incident pump energy was 25%, the efficiency of energy absorption was 32%, and the differential efficiency was 50%. The lasing band had a maximum at lambda equals 1. 17 mu and the half-width was DELTA lambda greater than 1000 cm** minus **1. Stimulated emission of radiation by the F//2** minus centers was observed when the pump laser was operated under free-running conditions (smooth pulses) and the efficiency measured relative to the incident pump energy was then 0. 5%. An efficient LiF:F//2** minus laser with a spectrally narrow and continuously tunable emission line was constructed.
