By using an open-resonator configuration, cw laser oscillation at 4.9 ..mu..m has been obtained on the 2 ..-->.. 1 vibrational transition of CN/sup -/ impurities embedded in KI. Population inversion in this device is produced by direct optical pumping of the first-overtone transition of CN/sup -/ at 2.42 ..mu..m with a tunable (F/sub 2//sup +/)/sub A/ color-center laser. By using a closed resonator, simultaneous pulsed laser output has been observed from the 3 ..-->.. 2 and 2 ..-->.. 1 transitions of CN/sup -/ following long-pulse pumping of the second-overtone transition with the recently developed high-power NaCl:F/sub 2//sup +/:O/sup 2-/ color-center laser.
