The invention thus provides a laser medical apparatus characterized in that the optical fiber unit comprises a large number of fibers each having a polygonal section. A protective board prepared from a laser-permeable material is detachably fitted to the laser output end face of the hand piece and laser beams issued from the source with a prescribed distribution of energy intensities are conducted through the optical fiber unit composed of fibers having a polygonal section for equalizing the energy intensity distribution laser beams are radiated over a broad area without irregularities and medical treatment can be undertaken uniformly in a short time. The protective board detachably fitted to the hand piece enables laser beams to be radiated with the hand piece in contact with the patient's diseased spot, so the hand piece can be accurately held during the medical operation and an efficacious medical treatment is ensured.Other References
