Interaction of Intensive ns-Laserpulses with Biological Matter
Q- switched lasers emitting lightpulses with duration of some nanoseconds have been introduced to medicine increasingly. On focussing these intensive lightpulses into (biological) matter shockwaves are produced due to the generation of a plasma, which are able to interact with objects and lead to its destruction. The propagation of this shockwaves and the effects at boundaries -are being studied experimentally on focussing intensive laserpulses onto the surface of biological tissue or into biologically comparable media (e. g. 0.9% NaCl- solution). Experimental results should show how to understand elementary mechanisms and point out the many unknown factors and parameters which can hardly be measured.
