Description

Bandwidth effects on laser-plasma interaction were investigated with a 1/4-μm laser. Planar targets were irradiated with a 1- to 40-cm-1 bandwidth laser at I = 1 x 1013 -4 x 1015 W/cm2. Above 3 x 1013 W/cm2, stimulated Brillouin scattering (SBS) was observed with 1 cm-1 light. This process was strongly reduced with a 40-cm-1 light. Evolution of the convective SBS was studied with 1-D fluid simulation code. Bandwidth effect on the SBS growth was discussed to compare the theoretical prediction and experimental results. The scalelength dependence exists for the SBS reduction with a broadband laser. (author)
