II-VI Incorporated announced the introduction of a new generation of pump laser diodes that achieve a high output power of 22 W from a single chip. Advances in the power of individual laser diodes further represent a cost advantage in laser systems. II-VI’s new laser diodes achieve 22 W of output power or 22% more than the existing product, enabling fiber laser designs with fewer emitters for applications such as cutting, welding, brazing and laser additive manufacturing. The 22 W pump laser diodes are available at 915 and 976 nm. The laser chips feature a 190 µm wide output facet designed to achieve optimum coupling efficiency into the widely-used 200 µm core fibers. The chips include II-VI’s proprietary E2 front mirror passivation that prevents catastrophic damage to the laser, even at extremely high output powers. The new chip generation successfully completed qualification with 4000 hours of accelerated aging.
