Abstract

The construction peculiarities and output parameters of two YAG:Nd lasers of high quality output radiation using a two-pass amplifier with a phase conjugated mirror are discussed. The first one has the following parameters in each of two channels: pulse energy at 1064 nm - 1900 mJ, at 532 nm - 700 mJ, at 355 nm - 250 mJ, at 266 nm - 130 mJ; beam divergence 0.3 mrad; line width 0.01 cm^-1; pulse duration 8 ns; repetition rate 1-5 Hz. The output parameters of the second one whose construction is based on the single flash lamp surrounded by four laser rods (one of the master oscillator, three others of the amplifier) are; pulse energy at 1064 nm - 350 mJ, at 532 nm - 130 mJ, at 266 nm - 25 mJ; energy stability at 1064 nm - 1.5%, at 532 nm - 4.5%, at 266 nm - 9.0%; repetition rate 1.15 Hz.
