Self-focusing of tightly focused laser beams
Applied Optics, 2015Laser-induced damage (LID) thresholds of pure fused silica have been measured with single-temporal-mode nanosecond pulses at 1.064 μm. The laser beam was focused by spherical lens or axicon into 2.7 μm diameter spots with identical cross-sectional distribution of the central lobe irradiances.
