DOUBLE-WAVE AND DOUBLE-CHANNEL TUNABLE CARBON DIOXIDE LASER WITH FOLDING RESONATOR

摘要

FIELD: laser engineering; developing lasers and spectrometers around them. ^ SUBSTANCE: proposed laser has case accommodating resonator. The latter has two discharge channels, output mirror, two turning mirrors, and spectral selective member (diffraction grating). The latter is disposed opposite first discharge channel in adjusting unit secured on butt-end of hollow cylinder joined through elastically deformed part to cylindrical bush. Disposed on external surface of hollow cylinder are movable lever and supporting flange rigidly fixed together. Output mirror is disposed on adjusting mechanism between second discharge channel and through hole provided in supporting flange and movable lever. One end of the latter is kinematically coupled with electromagnet and other one, with butt-end surface of cylinder flange. ^ EFFECT: enhanced precision of wavelength selection and radiation power stability. ^ 3 cl, 5 dwg
