Description

technical field [0001] The invention relates to a laser therapeutic apparatus, in particular to a multipurpose high-power semiconductor laser therapeutic apparatus used in the field of laser medical operation treatment. Background technique [0002] In the field of laser medicine, high-power lasers mostly use doped crystals as the excitation medium, and the excitation light source is a lamp pump or a semiconductor pump source. However, the above-mentioned high-power lasers have problems such as complex optical structure, low photoelectric conversion rate, short life, poor stability, large volume, and high price. At present, in high-power laser medical equipment, almost single-wavelength solid-state lasers are used, which has certain defects in clinical application. [0003] In recent years, semiconductor laser technology has developed rapidly. Semiconductor lasers have the characteristics of small size, high photoelectric conversion rate, wide range of laser wavelength sel...
