The Effects of Self-Focusing on Laser-Induced Breakdown


The polarization dependence of laser-induced breakdown and beam distortions in the transmitted time integrated spatial profile were used to determine the effects of self focusing on picosecond breakdown threshold measurements in fused silica and NaCl. The results at 1.06 and 0.53 μm laser wavelength indicate that, for focused geometries, no significant self-focusing occurs in these materials until the beam power approaches P2, the second critical power for self-focusing.
