Abstract

The present invention discloses a multi-single-tube high-power fiber-coupled diode laser which comprises a shell, two oppositely arranged semiconductor laser groups for generating two groups of N parallel beams, a reflector group which is between the two semiconductor laser groups and is used for combining two groups of N parallel beams to be a nearly square light spot, and a coupling lens for coupling the light spot to an optical fiber. According to the laser, the laser transmission optical path can be reduced, thus a package structure is compact, the adjustment is convenient, the correction of errors caused by laser chip assembly and beam collimation is facilitated, and thus a light beam with high power and good quality is obtained.

Description

technical field [0001] The invention relates to a semiconductor laser, in particular to a multi-single-tube high-power fiber-coupled semiconductor laser. Background technique [0002] As a new generation of lasers, semiconductor lasers are widely used in industrial processing, military, medical, security and other fields due to their advantages of high efficiency, long life, and small size. With the vigorous development of fiber lasers and the continuous improvement of the demand for high-power fiber laser pump sources, the rapid development of high-power, high-beam quality semiconductor lasers has also been promoted. At present, there are mainly two types of semiconductor lasers on the market, namely single-tube semiconductor lasers and multiple single-tube semiconductor lasers. Most single diode lasers are suitable for low power applications. In high-power occasions, multiple single-tube semiconductor lasers are often used, such as figure 1 Shown is the axial stepped st...
