PURPOSE:To simplify the constitution of the entire 5 apparatus and to make the adjustment of laser output accurate by controlling the driving number of a plurality of semiconductor lasers housed in the main body of the laser apparatus according to the preset value. CONSTITUTION:A plurality of semiconductor lasers 4 are provided in a laser oscillating part 1. In a control part 3, an output setting part 10, which sets the output of the laser light from a main body A of a laser apparatus, and a control device 11, which controls the driving number of the semiconductor lasers 4 according to the preset value 17 set with the output setting part 10, are provided. Thus, when the laser-apparatus main body A is used, the output of the laser light from the laser-apparatus main body A is set by the pushing operation of an operating button 15 of the output setting part 10. The opening and closing operations of each contact point 13a in a power supply device 12 are controlled with the control device according to the preset value set with the output setting part. Thus, the driving number of the semiconductor lasers is controlled. |
