Tuning of PbSe Lasers by Hydrostatic Pressure from 8 to22 μ

Abstract

This paper reports the tuning by hydrostatic pressure of the wavelength of emission of a PbSe laser from 7.5 to 22.3 μ in the infrared. Also discussed are the possibilities for further extension of the emission wavelength, the physical studies thereby rendered possible, the possibility of tunable devices, and the extension of similar ideas and techniques to other semiconductors of the PbSe family.
