Paper Abstract

Excimer lasers are used for many medical applications, e.g. angioplasty and ophthalmology. In the medical field fiber delivery systems are predominantly used with XeCl-lasers (308 nm) up to now. The best suited core-material for the moment is undoped synthetic fused silica with high OH-content. At 193 nm transmission of these fibers is limited by high nonlinear absorption and color-center generation leading to increased absorption. For ArF-lasers at 193 nm wavelength new results of the nonlinear transmission properties of improved fused silica fibers are presented and discussed, taking the following parameters for medical laser-fiber- systems into account: fiber length, fiber diameter, fluence, and repetition rate. Finally the results are discussed regarding the difference in the generation of color centers.
