Abstract :
We have conducted transmission measurements in laser modified and pristine sites of fused silica substrates at 355 nm, 532 nm and 1064 nm. Multiphoton absorption at 355 nm was considerably stronger in the modified regions compared to pristine sites and was strongly dependent on the excitation wavelength.
