Tunable carbon monoxide laser

The spectral and energy (power) characteristics of a sealed carbon monoxide laser were investigated utilizing selective and nonselective optical resonators. A 100 line/mm diffraction grating with a blaze angle of 30° was used in the selective resonator. It served as the laser coupling-out element. The emission spectrum of the tunable CO laser contained 90 lines in the range 1626–1910 cm^–1, with powers of between 10 mW and 1.36 W. In the case of the nonselective resonator, 36 laser emission lines were obtained, having a total power of around 13 W.
