The emission wavelength of a chemical HF laser was shortened by the use of molecular overtones as the active transitions in initiation of chemical reactions in SF/sub 6/--H/sub 2/S (HBr) --He mixtures by longitudinal electric discharges. The efficiency of conversion of the chemical energy into coherent radiation at the overtone frequency was approx.15% of the fundamental frequency. The output radiation intensity, 10/sup 3/ W/cm/sup 2/, was sufficient for the use of this laser as an overtone master oscillator in conjunction with an amplifier based on the H/sub 2/--F/sub 2/ chain reaction.
