摘要

针对于目前国内半导体激光加工熔覆光源主要依赖于国外进口的局面，研制了连续输出功率达10 kW的半导体激光熔覆光源。利用ZEMAX光学设计软件模拟半导体激光光路，包括光束整形、准直及聚焦透镜的设计等。实验中采用2只波长为915 nm和2只波长为976 nm的半导体激光叠阵，通过偏振合束和波长合束技术实现它的合束。由自行设计的聚焦系统进行了聚焦实验，结果显示，当模块工作电流为122 A时，光源最大输出功率为10 120 W，电-光转换效率为46%，在工作面的聚焦光斑为2.5 mm18 mm，可满足工业中大面积高速激光熔覆和表面热处理的要求。

Abstract

As civil diode laser cladding sources rely heavily on import from the occident

this paper developed a diode laser source which could continuous output ten thousands of watt powers. The light paths of the diode laser was simulated by ZEMAX

including the designs of beam arrangement

collimation lens and focus units. Four diode laser stacks with wavelengths of 915 nm and 976 nm respectively were used in an experiment and their beams were combined by the technologies of polarization combination and wavelength combination. A focusing experiment was performed by the focusing system developed by oursevles and the experiment results show that when an current of 122 A is inputted

the output power and the total electrical-optical conversion efficiency of this laser cladding source are 10 120 W and 46%， respectively

and the beam spot size is 2.5 mm18 mm at working surface. This diode laser source can meet the need of large area and rapid laser cladding and heat treatment in industry.
