A study was made of stimulated emission and amplification of light in lasers with active media consisting of alcohol solutions of rhodamines 110, 6G, and B, and of oxazine 17. The pulse repetition frequency was 10 kHz and pumping was provided by a mass-produced copper vapor laser of the ILGI-101 type. The dye lasers emitted in the range 530--720 nm. The efficiency of the oxazine 17 laser was 20% and the efficiency of the rhodamine 6G amplifier was 30% when the width of the laser emission spectrum was 0.8 cm/sup -1/. A Fabry--Perot interferometer was used to reduce the width of the spectrum to 0.04 cm/sup -1/, but this reduced the efficiency to 7%. The maximum output power was 0.6 W. The radiation was transformed to the second harmonic in the 265--360 nm range with an efficiency of 5%.
