Abstract

We conducted Z-scan measurements using ultrashort high-repetition-rate lasers and spectroscopic-grade fused-quartz cuvettes that had undergone macroscopic laser-induced damage in the course of the measurements. Visual observation of increased scattering of the laser beam from the damaged sites and Nomarski microscope images showing changes in the morphology of the damaged regions were used as the criteria for damage. Intensity- dependent open- and closed-aperture Z-scan studies produced profiles that are characteristic of the extent of the damage. The appearance of these unique signatures in any high-repetition-rate Z-scan measurement is a useful marker for timely recognition of occasional collateral damages that are associated with this type of study.
