X Photonics 976±0.5 nm, 220 W laser diode

The WS976220135-M from X Photonics is a high-power, wavelength-locked diode laser designed for demanding fiber laser pumping and direct industrial applications. Delivering 220 W typical output power at 976 nm, it utilises a multiple single-emitter coupling architecture to achieve exceptional beam quality and stability. Its narrow spectral width of 0.8 nm and wavelength-locking ensure efficient and consistent absorption in ytterbium-doped fiber lasers, enhancing power conversion and system stability during long-term operation.

Built on X Photonics’ precision diode assembly and automated optical coupling platform, this module integrates advanced 1040–1200 nm feedback protection and robust mechanical design for high reliability in continuous-wave operation. The 135 μm core fiber with 0.22 NA ensures high coupling efficiency and compatibility with standard pump combiner configurations. The module maintains stable performance across a 25 – 45 °C package temperature range, supported by effective thermal management for long-term durability.

The WS976220135-M is ideally suited for CW and pulsed fiber laser pumping, laser cleaning, and other direct diode applications requiring precise wavelength stability and high optical brightness. Its optimized lightweight package and proven reliability reflect X Photonics’ commitment to “The World’s First Quality” standard, providing OEM integrators with a dependable and high-performance pump source for next-generation fiber laser systems.
