Abstract

An AOM or self-oscillation pulsed thin disk Ho:YAG laser system at 2.1 µm with an average power in the 10 W range will be presented for laser lithotripsy. For the gain switched mode of operation a modulated Tm-fiber laser is used to produce self-oscillation pulses between 5 to 20 µs at mJ pulse energies that are available for a local heating of the stone material with a decomposition of the crystalline structure into calcium carbonate powder. Imploding water vapor bubbles between the fiber end and the stone material produce sporadic shock waves which help clear out the stone dust material.
