Abstract:
Laser action has been achieved with lithium (F(2)(+))(A) centers in additively colored KI. In preliminary measurements, this material has been tuned continuously between 2.72 and 3.67 microm. The material was coaxially pumped with a pulsed 1.73-microm Er:YLF laser, and (F(2)(+))(A) centers were produced by using a selective, two-step photoionization technique, These additively colored crystals have the practical advantage of being reusable after cycling between liquid-nitrogen and room temperature.
