Abstract
The generation of subnanosecond pulses by the combined effects of stimulated Brillouin scattering (SBS) and laser-induced breakdown has been investigated by obtaining simultaneous streak photographs of the spark, the backscattered and the transmitted pulses. The results demonstrate that the output from an excimer pumped dye laser can yield subnanosecond pulses with a duration of ≧20ps. The pulse shortening effect results from the nonlinear reflection properties of the Brillouin mirror and the strong absorption of visible radiation by the laser-breakdown plasma.
