X Photonics 976±0.5 nm, 9 W laser diode

The WS976009105-M from X Photonics is a precision-engineered 9 W fiber-coupled diode laser operating at 976 nm, designed specifically for high-stability laser pumping and direct photonic applications. Built on multiple single-emitter coupling technology, it delivers consistent optical output with excellent wavelength stability (976 ± 0.5 nm) and a narrow spectral width below 1 nm. The module’s high conversion efficiency of 43% ensures minimal electrical losses and supports long-term operational reliability under demanding industrial and research conditions.

Featuring a 105 μm core fiber with 0.22 NA, the WS976009105-M guarantees efficient power delivery and low beam divergence. Its integrated feedback protection (1020–1200 nm range, 30 dB isolation) secures the laser against optical back-reflections, protecting both the device and system optics. The unit operates optimally between 20 °C and 30 °C, with a wavelength temperature coefficient of just 0.03 nm/°C—ensuring precise spectral control essential for fiber laser pumping and wavelength-sensitive setups.

Engineered to meet X Photonics’ rigorous manufacturing standards, the WS976009105-M is housed in a robust, hermetically sealed package designed for high mechanical stability and thermal efficiency. It has passed 100% leak, burn-in, and performance tests under ISO 9001 quality protocols. Ideal for integration in ultrafast and CW fiber laser systems, the WS976009105-M combines compact design, reliability, and spectral precision—making it a preferred choice for OEM laser developers seeking wavelength-locked diode performance at 976 nm.
