Abstract

The presence of strong nonlinear absorption has been observed in laser modified fused silica. Intensity-dependent transmission measurements using 355, 532 and 1064 nm laser pulses were performed in pristine polished regions in fused silica substrates and in locations that were exposed to dielectric breakdown. The experimental results suggest that multiphoton absorption is considerably stronger in the modified regions compared to pristine sites and is strongly dependent on the excitation wavelength.
