Optically pumped pulse-periodic C2D2 laser

A pulse-periodic C₂D₂ laser with a resonant pumping by CO₂ laser radiation was constructed and investigated. Measures which could optimize the output radiation parameters were identified. The average output power was ~5 W at the emission frequency of 562.5 cm^–1 and the efficiency of conversion of CO₂ laser radiation was 2.9%. The energy of a single pulse was ~100 mJ.
