Abstract
This semiconductor laser treatment unit is constructed of a laser radiation device 1 and a control box 67 which houses a control mechanism for controlling this laser radiation device 1. The laser radiation device has at its tip a cap 3 which has a pair of touch sensors 69 in the vicinity of a laser emission aperture 68, multiple semiconductor lasers 10, and a series of lenses which make the laser beams emitted from the semiconductor lasers parallel and also focus them to a single point to form a laser beam for use in medical treatment. Further the unit is provided with a means of adjusting the degree of convergence required to create a medical treatment laser beam from the laser beams emitted from multiple semiconductor lasers, a means of precisely and easily determining the status of laser beam emission, thus making the device easier to use and enhancing its safety during use, and a means of eliminating any unpleasant sensation caused to the patient by the touch sensors 69.
