| Abstract: | The laser processing is widely used in the welding of metallic materials, cladding, surface hardening, and other industrial fields. The semiconductor laser has many advantages, such as small volume and weight, high efficiency, maintenance-free, low cost, short wavelength, and so on. In this paper, a 2 218 W high-brightness fiber-coupled module was designed and overall assembled by using 48 conduction cooled diode laser arrays as light-emitting units under a major thoroughfare of industrial water-cooling condition. The emitting wavelength of the diode laser arrays were 808, 880, 938, 976 nm, respectively. The high brightness module can make the flexible manufacturing directly applied in the industrial. |
