ABSTRACT:
The present invention is for the purpose of providing a medical laser irradiation apparatus which applies laser beams of two or more wavelengths, incapable of transmitting in a quartz optical fiber, through the use of an optical fiber cable, with this medical laser irradiation apparatus being easy to handle and producible at a low cost, and also capable of making irradiation through the use of a relay optical fiber cable comprising a quartz optical fiber. For this purpose, this apparatus is composed of a laser irradiation apparatus to output laser beams of a plurality of wavelengths capable of being transmitted by a quartz optical fiber, and two or more kinds of irradiation optical fiber cables including an optical fiber cable having a quartz optical fiber and containing a solid state laser medium and/or a nonlinear optical crystal at its tip portion. Thus, by using properly the plurality of irradiation optical fiber cables, it is possible to apply laser beams of two or more kinds of wavelengths, incapable of being transmitted by a quartz optical fiber, to an appropriate place through the use of one small-sized laser generating means.
