A description is given of a cw chemical HF laser and its characteristics. The results are reported of investigations of the efficiency of conversion of the HF laser radiation into second harmonics and combination frequencies in LiNbO/sub 3/, LiIO/sub 3/, and Ag/sub 3/AsS/sub 3/ crystals. The most efficient conversion was achieved in proustite (Ag/sub 3/AsS/sub 3/) when the second-harmonic power was approx.3..mu..W and the fundamental-frequency power was approx.100 mW. Twenty-one emission lines were obtained in the 1.39--1.49 ..mu.. range. The HF laser radiation was converted to the visible range (0.522--0.516 ..mu..).
