Blue high-power diode lasers: One of the main applications is the welding of copper components, for example in electrical drive technology or power electronics. Its wavelength of 445 nm is absorbed by copper and copper alloys ten times better than infrared radiation, which ensures exceptionally smooth weld pools without pore formation. The highlight of the product range are the world's first commercially available blue diode lasers with 4 kW CW output power, which open up new areas of application, such as the deep welding of inverter assemblies. The most compact version of blue high-power diode lasers, the LDMblue lasers, are available with CW output powers of up to 2 kW and are particularly easy to integrate into machine and system concepts thanks to their space-saving 19" format (7 U).
