Minimally invasive procedures gain more and more importance in several disciplines of surgery. Medical lasers can significantly contribute to this development, since lasers can basically cut at the level of a single cell. However, most available medical lasers do not achieve this limit due to considerable collateral damage of the surrounding tissue in terms of thermal effects and shock wave propagation. The Picosecond Infrared Laser (PIRL) drives the ablation of tissue faster than thermal and shockwave propagation can occur in the surrounding tissue. Nevertheless, the picosecond time regime is long enough to avoid ionization of the tissue creating toxic free radicals. We will discuss different types of medical lasers, and medical results of the PIRL project on the macroscopic and microscopic level will be shown. Future projects with respect to possible fiber applications will be presented.
