Abstract

PURPOSE:To enable to perform a high speed operation even when a laser output detector of a slow responding speed is used by a method wherein the output of a laser oscillator is memorized in a memory, the output patter is arithmetically operated by the output and the output command of the output detector, and the oscillator is controlled using the result of the above arithmetic operation. CONSTITUTION:The output pattern memory 8, wherein the output pattern of the laser oscillator 1 was memorized, is connected to an arithmetic operational unit 7, and the signal and the output command sent from the laser output detector 4 are applied to the device 7. The output of the detector 4 and the output pattern sent from the output command 5 are arithmetically operated, and the result is inputted to the oscillator 1 as a laser oscillator input 9. Also, the output of the oscillator 1 is emitted to outside as a laser output 3 through the intermediary of the partial reflection mirror 2. At this time, the reflected signal sent from the reflection mirror 2 is added to the detector 4, and the laser output is made to correspond to the output command using the above as the signal to be applied to the device.
