Abstract

For laser lithotripsy with μs pulses there have only been dye lasers available with fixed pulse length and pulse shape. The development of a pulse stretched Alexandrite laser offers the possibility to control these parameters, thus to find their optimum for lithotripsy. This paper describes the laser system and reports on the first results that have been achieved concerning fiber transmission with extended pulses, fiber damage thresholds, fragmentation rates and a stone/tissue detection and feedback system to avoid adverse tissue effects.
