This invention relates to a device for irradiating laser beams to be used when applying laser beams to an animal, human, for example, tissue to perform incision, transpiration, or thermotherapy on the tissue, or when expanding a constricted part caused by cholesterol in a narrow passage in an organic tissue, for example, a blood vessel of a human body. A plurality of optical fibers to transmit laser beams emitted from the laser beam generator and at least tips of said fibers are exposed as cores and each core part is integrally covered with a cladding material which is used as a laser beam emitting body. |
