Abstract

Waveform conjugation of narrowband KrF lasers with linewidth 0.02 cm-1 and divergence 10-4 rad was investigated. By means of Brillouin scattering in SF6 gas, the 12 ns duration pump pulse was compressed up to 1.5 ns with energy efficiency about 80% and the laser beam divergence retention. The waveform conjugation under thermal Raleigh scattering in hexane, heptane and hot water was also investigated. The maximum efficiency in hexane was about 10% and scattered pulse duration 2.5 ns. Waveform conjugation in a wide region of liquid absorption coefficients was also observed.
