The pulsed dye laser (wavelength 504 nm, pulse duration 1 μs) is widely used for fragmenting urinary and biliary calculi. In this study, the performance of this laser was compared with pulsed dye lasers producing pulse durations of 8 and 20 μs. Fragmentation thresholds and fragmentation rates were measured using a variety of urinary and biliary calculi. Effective fragmentation of urinary and biliary calculi was obtained with 1‐μs and 8‐μs pulse durations, but satisfactory fragmentation could not be achieved at 20 μs.
