Paper Abstract

A two-color (λ1 = 10.6 ÷ 11.3 μm and λ2 = 5.3 ÷ 5.65 μm) laser with an original V-shaped cavity has been developed and experimentally realized. The radiation (λ1 and λ2) was coupled through the zero order of the grating along one direction. Production-type GL-501 (CO2) and GL-509 (CO) electric-discharge tubes with non-transmitting mirrors were mounted at the shoulders of the three-mirror V-shaped cavity. The third mirror was a diffraction grating with 100 lines/mm, which was mounted at the cavity vertex and operated by the non-autocollimation scheme in the first order for the lasing on CO2 molecules and in the second order for CO. As a result of the tuning of the diffraction grating, we obtained a stable oscillation on more than 30 pairs of lines (in the range of 10.6 - 11.3 μm for CO2 and in the range 5.3 0 5.65 μm for CO) with the output power of ~10 W (CO2) and ~1W (CO) for the strong lines at the single-mode regime.
