Paper Abstract

Alexandrite laser system which emits a wavelength of 750 nm has been recently proposed as a substitute for the pulsed-dye laser (504 nm) for laser-lithotripsy. We have carried out in vitro lithotripsy trials in order to evaluate the efficiency of a flashlamp pumped Q-Switched Alexandrite laser. The experimental system was performed by an alexandrite laser (Quanta-System Inc.), with a pulse energy between 40-80 mJ/pulse, at a repetition rate of 10-20 Hz; and a pulse duration of 250-300 nsec. This system permits the use of 320-500 micrometers fibers.
