title: [Experimental use of a q-switched YAQ high-performance laser as a surgical tool].
abstract: A q-switched YAG-laser has been investigated as an "optical knife". It was possible to cut rat liver without bleeding but there was no influence of the repetition frequency on the cutting effect. Otherwise, the width of the necrotic zone could be changed evidently more by using the q-switch-technique than by using a cw-laser. First experiments with pig liver showed, that larger vessels can be cut without bleeding by using laser beams as an "optical tool".
