Various technologies based on different light—tissue interaction phenomena have been developed for medical applications. Now the progress in the area of laser medical technologies depends more and more from the design of a special fiber—optical tools1'2 . Thus the flexible fabrication technique for such fiber tools manufacturing is needed . These tools should serve for a laser beam forming ( local spot or volume irradiation, inclination of irradiation direction, spot size and the intensity distribution variation, etc.), for the most effective use of laser power in a distinct medical operations. Traditional optical elements ( i.e. lenses, prisms, mirrors ) could not be used as for laser treatment in local difficult—to-reach places of the body in the most of otolaringological,proctological, neurosurgery and eye microsurgery operations as for endo—, laparo- and torocoscopical laser operations as well. The creation of a number of fiber-end optical components FEOC ), such as lens—ended fibers, scatterers,side—fiber components, etc. gives a broad way for laser medicine applications independently from the localisation of an object of treatment (internal or external tissues of pacient). These fiber tools could be based on the fiber tip forming , its orientation relatively the fiber axis or/and on partial changing the total internal reflection conditions upon the determined length of fiber. These irradiation—forming FEOCs having about the fiber diameter size it is possible to include in endoscopic laser complexes for the solving of different tasks of modern medicine and diagnostics.
