<title>Double-mode CO2 laser with complex cavity for ultrasensitive sub-Doppler spectroscopy</title>

Abstract

We report on obtaining generation of & CO2 laser with a phue-anisotropy three-mirror cavity operating in a linear orthogonal polarized double mode regime. It wss proved that in a double mode CO2 laser with an internal absorbing cell the saturation of the absorbing medium can be significantly reduced with the help of a three-mirror telescopic cavity. Narrow non-linear reeonanc of high amplitude were obtained in a C02/SF6 isier with the pha.ee-anyaotropy cavity.
