Abstract
At present, the two lasers including Nd:YAG pulse laser and Nd:YAG high frequency laser, which can both produce laser with wavelength of 1064nm, are widely used in in medical, military, people’s livelihood and other fields. Their working material is Nd:YAG crystal. The appearance of passive Q Nd:YVO4 crystal of graphene quantum dots can improve the pumping efficiency of Nd:YAG high frequency laser and increase the peak power. In this experiment, the interference effect of the three lasers will be interfered with CCD, and the interference effect generated under different laser power and frequency will be measured. The interference mechanism of the three lasers will be analyzed to lay a foundation for their application.
