Abstract

In recent years laser technology has undergone a tremendous development. New laser sources have become available for routine applications which are now being introduced in various fields of medicine. In particular, excimer, pulsed dye, new solid state (Er:YAG, Ho:YAG, Alexandrite) and diode lasers exhibit promising characteristics in view of therapeutic procedures. At the same time optical fiber technology has been constantly ameliorated, primarily due to the growth of the telecommunication needs. Thanks to the manufacturing quality and to new types of optical fibers, it is now possible to transport through fibers the high power or energy which is often necessary to achieve therapeutic effects. As these fibers can have a thin diameter, new possibilities of treatment are being offered in that the laser beam can be brought inside the human body through natural openings or small incisions, thereby rendering more invasive procedure unnecessary. In this paper some aspects of power and pulse transportation characteristics of optical fibers are discussed and results of corresponding experiments are shown.
