Abstract
The invention relates to a laser light source device of a high-power semiconductor. A laser light source with high power, high light beam quality and small divergence angle is obtained by adopting a plurality of hectowatt-level laser stack array module through a beam binding technology and a beam expanding focusing technology. The laser light source device has light weight, small volume, high electro-optic conversion efficiency and long service life, overcomes the disadvantages of big volume, low energy efficiency, short service life and the like of chemical lasers, CO2 lasers and the fundamental frequency 1064nm Nd:YAG lasers of lamp pumps and semiconductor laser pumping and the like, realizes the high-power, high-brightness and high-quality direct input of the hectowatt-level lasers and can be directly applied to the field of laser processing. Under the condition of the same output power, the volume of a semiconductor laser is 1/3-1/10 the volume of other lasers, the operating cost thereof is 1/4-1/20 the costs of other lasers, and the service life thereof is 5-10 times the service lives of other lasers and can reach more than 10000 hours.
Description
technical field [0001] The invention relates to a high-power semiconductor laser light source device whose output power can be as high as several thousand watts. Background technique [0002] Because high-power semiconductor lasers have the advantages of small size, light weight, high efficiency, and long life, they have been widely used in laser processing (drilling, cutting, welding, surface processing, material modification, etc.), laser medical treatment (diagnosis, treatment, Surgery, cosmetology, etc.), laser display and scientific research, etc., have become comprehensive high-tech in the new century with rapid development, many achievements, wide penetration of disciplines, and wide application range. [0003] At present, CO is mostly used in laser processing 2 Lasers, lamp-pumped and semiconductor laser-pumped fundamental frequency 1064nm Nd:YAG lasers. [0004] CO 2 Lasers, by converting the thermal energy of combustion gases into laser energy, achieve megawatt-...
