Abstract

The embodiment of the invention discloses a laser device, a control system and a method for stabilizing the energy and the direction of a laser path. The laser device comprises a laser, a first reflecting mirror, a second reflecting mirror, a first detector, a second detector and an energy regulating mechanism. The first reflecting mirror, the second reflecting mirror and the energy regulating mechanism are sequentially arranged in the light path direction of the laser. The first detector and the second detector are used for detecting the position information of a light spot of laser on the first reflecting mirror and the sampling energy value of laser on the first reflecting mirror and the position information of a light spot of laser on the second reflecting mirror and the sampling energy value of the laser on the second reflecting mirror respectively. The first reflecting mirror and the second reflecting mirror are installed on two rotating regulating mechanisms respectively. The laser device, the control system and the method for stabilizing the energy and the direction of the laser path can effectively ensure the stability of the energy and the direction of the laser path.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a laser device, a control system and a method for stabilizing the energy and direction of the laser light path. Background technique [0002] Laser has the advantages of good monochromaticity, strong directionality, and high brightness. With the continuous development and progress of science and technology, laser technology is gradually applied to various fields. [0003] At present, laser technology is often used in the processing industry. During processing, the laser emitted by the laser is directly incident on the workpiece to be processed after passing through the beam transmission system. However, the inventors have found in research that due to the influence of various factors such as the laser itself, temperature and vibration, the laser energy incident on the workpiece to be processed and the position of the laser spot often change, which affects the processing quality, e...
