Ultrafast lasers have become a promising tool for micromachining and extremely precise ablation of all kinds of materials. Due to the extremely low energy threshold, thermal and mechanical side effects are in he sub micrometer range. The neglection of side effects enable the use of ultrashort laser pulses in a broad field of medical applications.
We demonstrate the feasibility of surgical procedures in different fields of medical interest: In ophthalmology intrastromal cutting and preparing of cornael flaps for refractive surgery in living animals is presented. Besides, the very low mechanical side effects enables the use of fs-laser in otoralyngology to treat ocecular bones. Moreover, precise cutting qualties can be used in fields of cardiovascular surgery for the treatment of arterio sklerosis. In the procedure presented the laser acts not only as the cutting tool, but may also be used to simultanesously control the cutting depth by interferometric analysis.
Further applications in the fields of dentistry and microstucturing of biocompatible materials are discussed.
