摘要	Aiming at satisfying demands in applications of laser cladding and heat treatment, a source for diode lasers with a continuous output power of 10 kW was developed. By taking diode laser stack as unit device, two diode laser stacks of 915 nm and two of 976 nm were utilized and combined using polarization combination and wavelength combination technology. At an input current of 122 A, the maxmum output power and the total electrical-optical conversion efficiency of this laser cladding source were 10 200 W and 46%, respectively. The thermal effect of key optical elements in the laser source was analyzed and an efficient thermal dissipation structure was designed. The maximum temperature of the lens decreased from 442.2 K to 320 K and the corresponding maximum von Mises stress reduced from 75.4 MPa to 14 MPa. This greatly improved the reliability of the laser source. 2019, China Science Publishing & Media LTD. All right reserved.
