New alternative for laser lithotropsy-long pulse passively q-switched solid-state laser with fiber-based resonator

摘要

Abstract: This paper presents an overview of the important processes which are responsible for stone fragmentation. The efficiency of these processes in dependence of wavelength and laser pulse duration is discussed. Beside shockwaves and cavitation phenomena the role of a compressional shock acting on the stone and the plasma confinement is emphasized. As a conclusion the concept of a passively Q- switched solid state laser with a fiber-based resonator which prolongs the pulse duration is presented. !5
