Optical catheters based on silver halide infrared fibers

Laser power transmission, luminescence, mechanical behavior and effects of various thermal treatments have been investigated on mixed sliver halide crystals. This knowledge may suggest ways of optimizing the fabrication of optical fibers from such crystals. Anti-reflection coating for high-power 10.6 micrometer light transmission was studied both on crystals and fibers. Laser power transmission and mechanical properties of the fibers also have been investigated. On the basis of these experiments the prototype of the medical catheter was produced and surgery experiments with this catheter have been performed.
