摘要
The present invention was stabilized with a laser processing device and processing the output of sound using a first diffraction optical element relates to a method, and more particularly, can control the amount of light radiated on the object to be processed, regardless of the amount of laser light emitted from a laser generating device, it is possible to determine whether or not the intermittent laser oscillator outside of the dwell time of the laser generator, to address the instability of the output the output interrupted based on the principle of the instability of the output of the laser oscillation in the laser oscillation time, that using the first order diffraction of the acoustic optical element to provide the uniformity of the workpiece machining apparatus and a laser output stabilizing relates to processing methods. ; device to stabilize the laser output was processed by using the first-order diffraction of the acoustic optical element according to the present invention, ; processing for processing a workpiece using a laser In the apparatus, ; laser generator and to generate a laser; ; and intermittent high-speed optical switch that determines whether or not the laser generated from the laser generator; ; peak modulation of the laser light for adjusting the optical splitter output is irradiated to the workpiece; doedoe configuration including the work of the high-speed optical switch and the laser generated by the variable optical splitter to the first diffraction by the first order diffracted laser characterized in that the processing. ; can be removed from the instability of the output of the present invention, it is possible to keep the output of the laser processing apparatus can continue to ensure a uniform processing of the workpiece It is.
