This paper looks back on the transmission of acoustical shock waves via optical fibers. After that it presents recent results on an optical and acoustical system of a new combined endoscopical laser and ultrasound surgical therapy (LUST) for coagulation and tissue disintegration. Theoretical calculations concerning the transmission of acoustic energy via optical fibers are shown. In first experiments on the transmission of high power ultrasound via a silica fiber of 800 mm length a longitudinal elongation of up to 30 micrometers at the distal end with a simultaneous laser transmission was achieved. A magnetostrictive ultrasound transducer with a frequency of 26 kHz and a Nd:YAG laser (25 W cw) was used.
