The M980±10-150-D400/22-C2L-APK is a high‑power, fiber‑coupled semiconductor diode laser module engineered for demanding OEM integration. Delivering up to 150 W of continuous‑wave optical power through a 400 µm core fiber, this module is optimized for applications requiring reliable 980 nm pumping, high brightness, and excellent electro‑optical efficiency. Its central wavelength is nominally 980 nm with a narrow 5 nm FWHM spectral width, making it an ideal pump source for ytterbium‑doped and erbium‑ytterbium‑doped fiber lasers and amplifiers, as well as for medical, industrial, and scientific systems that rely on the standard 9xx nm pump band.

Designed for straightforward fiber integration, the laser output is delivered through a 400 µm core, 0.22 NA multimode fiber terminated with an industry‑standard SMA905 connector. This configuration balances high power handling capability with robust coupling and alignment tolerances, supporting stable operation in both laboratory setups and compact OEM platforms. Compared with similar 980 nm pump modules on the market, this unit combines high output power with a well‑controlled beam profile at the fiber exit, enabling efficient coupling into downstream optics or active fibers.

The module features a threshold current of 0.9 A and operates typically at 17.0–17.5 A, with a corresponding operating voltage around 15.6–15.8 V. A high slope efficiency of 9.1 W/A and a power conversion efficiency of approximately 55% place this module in a competitive range compared to other high‑performance 980 nm pump diodes, reducing electrical power consumption and thermal load. These parameters are particularly beneficial for compact and mobile systems, where minimizing heat dissipation and power supply requirements is critical.

To facilitate integration, the M980±10-150-D400/22-C2L-APK incorporates built‑in thermal monitoring and an aiming beam. The internal thermistor, specified at 10 kΩ at 25 °C, allows precise monitoring and stabilization of the laser temperature via an external TEC controller, which is essential for maintaining wavelength stability and long‑term reliability. A 650 nm, 2 mW red aiming beam provides a visible guide to the infrared output path, simplifying alignment tasks and minimizing setup time in optical systems where the main 980 nm beam is not visible to the eye.

The diode module is rated for an operating thermistor temperature range of 25–35 °C, ensuring stable performance when properly heat‑sunk and temperature‑controlled. It tolerates an operating humidity below 75% and a broad storage temperature range from –20 °C to +80 °C, supporting safe transport and storage in diverse environments. These ranges are comparable to those of other industrial‑grade pump laser modules and help ensure dependable behavior in both prototyping and high‑volume OEM deployments.

Electrical interfacing is supported by dedicated pins for the laser diode anode and cathode, thermistor, photodiode, fiber connection sensor, and the red aiming beam supply and ground. The integrated monitor photodiode enables feedback‑controlled operation for power stabilization, which is often a requirement in precision fiber laser and amplifier systems. The fiber connection sensor functionality further contributes to system safety and interlock schemes by enabling detection of the fiber coupling status, helping to prevent inadvertent free‑space emission at high power levels.

As an OEM fiber‑coupled diode laser module, the M980±10-150-D400/22-C2L-APK is intended exclusively for integration into complete laser systems and equipment. It is not supplied as a stand‑alone, user‑operable laser product and is therefore not classified as a finished laser device under IEC or FDA/CDRH regulations. System manufacturers integrating this module are responsible for determining the final laser classification and for ensuring that their completed products meet all applicable safety, labeling, protective, and regulatory requirements. When integrated with suitable cooling, drive electronics, and safety controls, this module forms a powerful and efficient building block for advanced fiber laser pumping, medical therapy systems, materials processing tools, and research‑grade photonics platforms.
