Abstract

The invention relates to a control device for laser constant power output and a laser processing device. The control device emits a laser beam through a laser, a power detection module rapidly detectsa single pulse energy signal value of the laser beam, a power correction module obtains a power correction value according to the single pulse energy signal value and a preset laser power value, andtherefore, the laser is controlled to output a laser beam with constant power according to the power correction value. In the detection process, the single pulse energy signal value can reflect the pulse laser energy of each time point, and therefore, the accuracy of detection is improved. The entire control process is simple and fast, and the function of the quick, accurate and stable power output of the laser can be achieved.

Description

technical field [0001] The invention relates to the field of laser control, in particular to a control device for constant power output of a laser and laser processing equipment. Background technique [0002] With the development of laser technology, the application fields of laser processing are becoming wider and wider. At the same time, the requirements for fine and precise processing of laser processing are getting higher and higher, so the requirements for the stability of laser output power are also getting higher and higher. However, during the use of the laser, the laser power may experience different degrees of power attenuation over time, as well as some other unstable factors. Constant power output has become an important performance index of lasers. [0003] The exemplary constant power output control method is generally adjusted by using the detected average power value as a feedback signal. The adjustment process is slow and prone to interference, so the outpu...
