In the process of crystal production, due to the purity of the material, production technology and other reasons, the light absorption uniformity of the crystal will be affected, thus affecting the crystal efficiency; After absorbing electromagnetic waves, the electromagnetic wave energy is converted into heat energy, which causes the internal temperature of the material changes , so that the internal heat absorption of the crystal is nonuniformity, resulting in large deformation. Therefore, it is of significant guiding principle and pratical value to study the effect of optical absorption coefficient of laser crystal material on laser output and frequency conversion efficiency. The laser power before and after passing through the sample is monitored in real time by using the difference principle of dual-optical paths, and the sample is rotated to reach the best test point, so as to obtain the laser crystal absorption coefficient. • The dual-optical path design can monitor the laser power in real time to ensure the accuracy of the test results • Different wavelength lasers are matched according to the characteristics of the sample • The sample holder can be customized according to the sample to be measured • The measurement results are intuitive and storable for subsequent processing and analysis • Simple to operate and easy to use
