Description
technical field [0001] The invention relates to the technical field of laser detection applications, in particular to a laser beam parameter measurement device. Background technique [0002] With the development of science and technology, laser technology has played a pivotal role in the construction of the national economy. It is widely used in optical display, optical information processing, optical communication, optical medical treatment, optical manufacturing, optical detection and other fields. At present, the application degree of laser technology has become one of the important symbols to measure the advanced nature of a country's industrial technology. [0003] The quality of laser beam is an important standard to measure the performance of laser products. The scientific evaluation of laser beam quality is of great significance to the design and application of lasers. In 1988, Siegman suggested the use of M 2 Factor describing the laser beam quality, M 2 The fac...
