X Photonics 793 nm, 500 W laser diode

The 793DA500220-II is a high-power, fiber-coupled diode laser optimized for 2 μm fiber laser pumping. Delivering up to 550 W of optical output power at a typical 796.5 nm wavelength, it offers excellent efficiency and spectral stability. The laser’s narrow spectral width of 6 nm and high coupling precision through a 220/242 μm fiber with 0.22 NA ensure uniform energy distribution and consistent optical performance in high-demand laser systems.

Built on multiple single-emitter architecture, the module integrates advanced optical alignment and superior thermal control to achieve a 39% electro-optical conversion efficiency. Typical operating conditions of 22 A and approximately 63 V maintain a stable optical output with excellent wavelength control. Its 30 dB back reflection isolation within the 1850–2150 nm range effectively protects against feedback, enhancing the reliability and lifespan of both the pump module and the overall fiber laser system.

Engineered by Shenzhen Xinghan Laser Technology Co., Ltd., the 793DA500220-II demonstrates outstanding thermal and mechanical stability under continuous operation. With an operational temperature range of 5°C to 45°C, it is designed for precision and endurance in industrial and scientific environments. This module is ideally suited for high-power fiber laser pumping, precision materials processing, and research systems where performance consistency and optical efficiency are critical. It exemplifies X Photonics’ leadership in high-power diode laser technology and its dedication to world-class laser manufacturing quality.
