Paper Abstract

The heating and the sounding pulse are generated by the same laser. The laser output radiation is split into two independent channels, one of them is converted into an ultraviolet picosecond pulse by means of backward stimulated scattering. When a 3 - 10 ns pulse is produced by a Q- switched laser, the temporal compression of the sounding pulse is performed with a cascade Brillouin and Raman backward stimulated scattering. When a 0.1 - 1 ns pulse is produced by a mode-locked laser, the sounding pulse compression is achieved with a backward stimulated Raman scattering. The beam is then frequency-doubled into 315 nm in a BBO crystal. The ultraviolet pulsewidth is about 10 - 20 ps and its energy is larger than 0.2 mj.
