Optical pumping of vibrational overtones in KI:CN-infrared lasers

Technical Report ·
OSTI ID:6085274

By using open-resonator configurations, continuous-wave laser oscillation at 4.9 micro m was obtained on the 2=1 vibrational transition of CN/minus/ impurities embedded in KI. Population inversion in this device is produced by direct optical pumping of the first-overtone transition of CN/minus/ at 2.42 micro m with a tunable (F/sub 2//sup +/) A color-center laser. By using a closed resonator, simultaneous pulsed-laser output was observed from the 3=2 and 2=1 transitions of CN- following long-pulse pumping of the second-overtone transition with the recently developed high-power NaC1:F2+:O2- color-center laser.
