A powerful and stable color-center laser based on a perturbed F/sup +//sub 2/ center has been demonstrated in additively colored NaCl:OH/sup -/ crystals. The OH/sup -/ impurity has been positively identified as the key dopant for creating the color-center laser in NaCl. The laser tunes smoothly over the 1.41- to 1.81-..mu..m region with a maximum cw power of 1.25 W when pumped by a 9-W cw Nd:YAG laser operating at 1.06 ..mu..m. Laser operation for periods of several weeks has been monitored with no observable fading in output power. In addition, mode-locked pulses of 5-psec duration have been generated in a synchronously pumped arrangement, tunable from 1.47 to 1.73 ..mu..m with an average power of 450 mW at the peak of the tuning curve.
