Abstract

PURPOSE:To changeover a laser beam passageway by means of the output of a discriminant circuit and to prevent the occurrence of abnormal conditions, by a method wherein a plurality of laser oscillators independently driven are provided together with a laser output detecting circuit and a discriminant circuit. CONSTITUTION:Laser oscillators 1, 2 that can be driven independently by different power sources 3, 4 are provided. Laser beams are condensed by a beam transmission condenser 10 through a mirror 7 operated by a beam changeover means 8 and sent to an object 11 to be radiated. Part of the laser beams is allowed to be incident upon a beam detecting circuit 12 via a mirror 9 and its output is inputted to a laser output discriminant circuit 13. When the output exceeds the allowable range, the power source 3 is made to stop supply by a control signal, while the mirror driving source 8 and the power source are actuated. By so doing, when this constitution is applied to a laser scalpel, safety for a living body can be improved, while, in the case of the manufacturing process, quality thereof can be improved.
