Solid-state laser power measurement calibration method and device

Abstract

The embodiment of the invention provides a solid-state laser power measurement calibration method and device. The method comprises the following steps of carrying out photoelectric conversion on an optical signal emitted by a solid laser to obtain a voltage signal corresponding to optical power, converting the voltage signal corresponding to the optical power into a level quantized digital signal corresponding to the optical power, carrying out anti-pulse interference processing on the optical power level quantized digital signal, namely an optical power level quantized value, and then carrying out average filtering to obtain an optical power level quantized average value, obtaining a corresponding optical power level quantized threshold value revision value according to a preset threshold value, and performing segmented calibration according to the optical power level quantized threshold value revision value and a reference power value detected by a thermoelectric laser power probe located outside the solid-state laser to obtain an optical power output level quantization calibration value. By implementing one embodiment, the measurement feedback value of the photodiode type laser power probe can be corrected, so that the measurement feedback value is close to the actual power value of the solid-state laser.

Problems solved by technology

[0004] In actual work, there is a problem that the actual laser power of the generated laser does not match the required laser power, which may be caused by factors such as xenon lamp attenuation, crystal damage, resonant cavity damage, optical path pollution, or water path pollution.

When the actual laser power does not match the required laser power, it will affect the use of the laser device
