GENERATION LINES SELECTOR FOR MOLECULAR IR LASERS

Applicability of several approaches to generation lines selection in molecular IR laser is investigated: diffraction grating placed in spite of one of cavity mirrors, Bragg mirror, inclined and reflective interferometers. A selector is proposed which combines advantages of Michelson interferometer with phase reflective interferometer, and which permits reliable selection of a chosen vibrationrotation generation line. The selector calculation is performed for the case of waveguide CO₂ laser. Two variants of schemes for laser tunability over generation lines are analyzed by using this selector.
