title: Stable, pulsed, color-center laser in pure KCl tunable from 1.23 to 1.35 microm.
abstract: Stable, tunable, pulsed laser operation based on the N(2) color center in additively colored pure KCI is reported. The laser tunes smoothly from 1.23 to 1.35 microm when pumped by a 1.06-microm Q-switched Nd:YAG laser at kilohertz repetition rates. 42-mW average output power at 1.28 microm was achieved for 1-W average incident pump power. No power fading has been observed over several weeks of day-to-day operation.
