Problems solved by technology

However, since the current laser drilling and laser cleaning mainly use the galvanometer to realize the two-dimensional scanning of the beam, it is limited by the maximum working angular velocity of the galvanometer. Taking the field mirror with a focal length of 650mm as an example, the current maximum scanning speed can only reach 10m / min, restricting the efficiency of laser drilling and laser cleaning

Description

technical field [0001] The invention relates to the technical field of laser scanning, in particular to an efficient laser drilling and cleaning optical system. Background technique [0002] Since the advent of lasers in the 1960s, laser technology has developed rapidly. Research has been carried out around the application of lasers. With the development of pulsed lasers, the emergence of pulsed lasers with high repetition rate and high peak power has promoted the development of laser drilling and laser cleaning applications. However, since the current laser drilling and laser cleaning mainly use the galvanometer to realize the two-dimensional scanning of the beam, it is limited by the maximum working angular velocity of the galvanometer. Taking the field mirror with a focal length of 650mm as an example, the current maximum scanning speed can only reach 10m / min, restricting the efficiency of laser drilling and laser cleaning. Contents of the invention [0003] The purp...
