cw operation and nitric oxide spectroscopy using diode lasers of Pb1−<i>x</i>Ge<i>x</i> Te

Abstract

cw operation at liquid-helium temperatures of junction lasers fabricated from the IV-VI alloy Pb1−xGexTe is reported. These lasers are current tunable and emit in the infrared between 4 and 6 μm. Preliminary high-resolution spectra of nitric oxide recorded near 5.3 μm by using these lasers are reported.
