The SPL BF98-40-5 laser bar combines power and beam quality featuring a 3-W/mm brilliance that helps reduce the complexity of coupling light into fibers. It allows diode or fiber laser systems for material processing to be made simpler and more cost-effective. Even at its maximum output of more than 60 W, the component has a long life.
The chip design of the laser bar uses a laser with a wavelength of 976 nm and high brilliance. The laser achieves the 3-W brilliance per millimeter and 1 mrad divergence angle at an optical output of 44 W. The lateral divergence of the beam emitted by the laser bar is between 6° at 30 W and approx. 9.5° at 60 W. Fiber-coupled diode laser systems are used predominantly in the automobile industry for vehicle chassis welding, soldering, and coating. The laser diodes are also often used for pumping fiber lasers. Tests show a drop in output of less than 1% after 4,00 -h of operation at an optical output of 65 W and a cooling water temperature of 25°C.
