Uncompromising performance

The 808 nm 30 W Fiber Coupled Diode Laser is a high-performance infrared source engineered for the most rigorous industrial, medical, and scientific applications. Operating at the industry-standard 808 nm pump wavelength, this module is specifically optimized for high-efficiency absorption in Nd:YAG and Nd:YVO4 laser crystals, providing the thermal stability and spectral accuracy required for high-end DPSS systems. Delivering a stable 30 W of continuous-wave (CW) output, the K808 series utilizes a high-brightness 200 µm or 400 µm multimode fiber core, ensuring exceptional energy density and beam quality. For total operational safety, it features integrated 30 dB feedback isolation, shielding the diode from harmful back-reflections in the 1020 nm–1200 nm range. Built with a high 45% electrical-to-optical efficiency and a rugged industrial housing with standard SMA905 termination, this module is the definitive choice for surgical medical platforms, laser soldering, and precision research.
