The deployment of fiber lasers for materials processing applications such as cutting, welding, marking, and additive manufacturing is accelerating, driving the demand for key components that lower the cost per watt of output power. The new laser diodes from Coherent achieve 50 W of output power, 40% more than that of the existing product, enabling high-power industrial fiber laser designs with fewer pump laser diodes.
“We believe that this is the first commercially available pump laser diode in the industry to achieve 50 W of output power,” said Dr.
The new 50 W laser diodes are available at 915 nm and 976 nm. The output facet width of the laser chips is available from 150 µm to 350 µm, enabling optimal coupling efficiency and output powers for a wide range of fiber laser designs. The chips include Coherent’s proprietary E2 front mirror passivation that prevents catastrophic damage to the laser, even at extremely high output powers.
Coherent offers pump laser diodes as bare dies, chips on ceramic submounts, and in fiber-coupled multi-emitter modules. Coherent’s broad portfolio of components for fiber lasers includes seed lasers, acousto-optic modulators, fiber Bragg gratings, kilowatt pump and signal combiners, as well as IBS-coated laser optics and micro-optics for high-power isolators.
