Two-stage shortening of pulses emitted from an XeCl excimer laser by stimulated Brillouin scattering

Ultraviolet pulses of duration down to 50 ps were generated by two-stage stimulated Brillouin scattering of the radiation from an XeCl excimer laser. This was done using truncated Brillouin scattering (TRUBS) on the surface of ethanol and subsequent amplifying of these pulses to an energy of 120 mJ.
