[0002] With the continuous development of laser technology, pulsed lasers have been widely used in optical experiments, laser processing, laser measurement, medical treatment and other fields. The main feature of pulsed lasers is that they can emit short pulses of high peak power. These pulsed lasers provide powerful energy in an instant and have very important application value. However, the use of pulsed lasers in experiments requires precise control of the laser parameters it outputs, and also requires ensuring that the relative position and angle between the laser and the experimental sample can be flexibly adjusted to achieve the best experimental effect.

[0003] Many existing experimental devices can only roughly adjust the position and angle of the laser, which cannot meet the needs of laser beam angle adjustment in precision experiments, especially when precise alignment of the experimental plate is required. The traditional adjustment method often leads to large angle errors, affecting the accuracy of the experiment, and it is inconvenient to replace the experimental plate. The plate is prone to shifting during laser irradiation, affecting the experimental results. The laser beam emitted by the laser has very high energy.
