X Photonics 915 nm, 120 W laser diode

The 915B120135 is a high-performance 120 W diode laser module engineered for precision fiber laser pumping and direct material processing applications. Operating at 915 nm, it delivers exceptional optical power stability through a 135 μm fiber core with a numerical aperture of 0.22, ensuring efficient light coupling and consistent energy output across demanding industrial environments. The design integrates multiple single emitters in a robust, hermetically sealed package, optimized for durability and high reliability under continuous-wave operation.

With a typical electro-optical conversion efficiency of 50%, this laser achieves superior thermal management and reduced power loss, maintaining stable wavelength and beam quality across a wide 5 °C–45 °C operating range. The advanced feedback protection layer (1040–1200 nm) enhances long-term stability by minimizing back-reflection damage, making the 915B120135 ideal for high-duty cycle operations in fiber laser systems. The unit’s mechanical integrity is further supported by X Photonics’ proprietary lid-flex design, minimising structural deformation during thermal cycling.

The 915B120135 finds widespread application in fiber laser pumping, additive manufacturing, and direct illumination systems where precision, consistency, and reliability are critical. Developed and manufactured by Shenzhen Xinghan Laser Technology Co., Ltd, it reflects the company’s commitment to “The World’s First Quality,” combining advanced diode packaging, optical alignment, and rigorous quality control to ensure performance suited for both industrial and scientific environments.
