X Photonics 976 nm, 750 W laser diode

The 976D750220-L represents X Photonics’ advanced generation of high-efficiency, wavelength-stabilised fiber-coupled diode lasers for demanding industrial and scientific applications. Designed around a 976nm emission wavelength, this module delivers a typical optical output of 750W through a 220μm fiber core, ensuring stable and uniform coupling for high-power CW fiber laser pumping systems. With precision thermal management and sub-micron diode bonding, it guarantees consistent wavelength stability and long-term reliability under continuous operation.

Built using multiple single-emitter diode coupling, the 976D750220-L provides robust feedback protection across 1040–1200 nm, enabling superior resistance to back reflections common in high-power laser architectures. Its typical electro-optical conversion efficiency of over 45% minimizes thermal load and ensures consistent performance even in demanding environments. Engineered for compact integration, the unit maintains a low lid and package temperature profile, supporting operation across the 20–30°C range with minimal wavelength drift.

This laser module is ideal for high-power CW fiber laser pumping, directed energy delivery and advanced manufacturing systems such as welding, cutting and additive processes. Its stability and durability make it equally suited for research environments requiring precision spectral locking. Backed by X Photonics’ stringent ISO-certified production and 100% in-line testing, the 976D750220-L exemplifies the company’s commitment to “The World’s First Quality” in diode laser engineering.
