Results are presented of an experimental investigation of a cw supersonic chemical laser utilizing D--O/sub 3/--CO/sub 2/ and H--O/sub 3/--CO/sub 2/ mixtures. For a D--O/sub 3/--CO/sub 2/ mixture the highest small-signal gain was 2.65 +- 0.13 m/sup -1/ and the lasing power reached 960 +- 50 W. In this case, the specific lasing power and chemical efficiency of the laser were 60 +- 3 Wxsecxg/sup -1/ and 18 +- 1%, respectively. For an H--O/sub 3/--CO/sub 2/ mixture under the same experimental conditions, the maximum gain of 2.45 +- 0.13 m/sup -1/ was achieved, which was only 8% lower than that for a D--O/sub 3/--CO/sub 2/ mixture. The downstream length of the inversion zone exceeded 20 cm. The mixing scale of the reagent streams was determined from the absorption of ultraviolet probe radiation by ozone.
