Title: Tunable two-mode Cr{sup 2+} : ZnSe laser with a frequency-noise spectral density of 0.03 Hz Hz{sup -1/2}

Abstract

An optically pumped cw laser on a Cr{sup 2+} : ZnSe crystal with a tunable (in the range of 2.3 - 2 .6 mm) wavelength, operating with generation of two axial modes, has been developed. It is shown that the minimum laser frequency-noise spectral density does not exceed 0.03 Hz Hz{sup -1/2}. Application of this laser in problems of Doppler and Doppler-free spectroscopy makes it possible to detect spectral absorption lines of gases with sensitivities of 5 Multiplication-Sign 10{sup -12} and 2 Multiplication-Sign 10{sup -10} cm{sup -1}, respectively (averaging time {tau} = 1 s). Having stabilised this laser with respect to the Doppler-free resonances of saturated dispersion of methane molecule, one can obtain a short-term frequency stability of 10{sup -15} - 10{sup -16} ({tau} = 1 s).
