Paper Abstract

Doping of alkali halide crystals with large amounts (10-3 to 10-2) of OH- and SH- defects can be used to drastically increase the production and stabilization of laseractive ionized F-aggregate centers like the F2+ and (F+2)A-centers. Using this technique tuneable cw laser operation is achieved for the first time with F2+ -centers in NaCl, KCl and KBr. Furthermore a short x-ray exposure reactivates centers thermally destroyed after RT storage. With F2+ -center lasers now the spectral range between o.8 and 2.o μm can nearly be covered. Slope efficiencies up to 6o % and single mode output powers in the range of 1 W have been obtained.
