Uncompromising performance

The 808 nm 8 W High-Brightness Fiber Coupled Diode Laser is a precision-engineered source optimized for applications requiring absolute spectral consistency and high energy density. Delivering a stable 8 W output through a fixed 105 µm multimode fiber, this module ensures maximum coupling efficiency and eliminates the potential for connector-end contamination or power loss. Engineered for medical and scientific reliability, the K808 series maintains high beam quality with a tight 0.22 Numerical Aperture. For mission-critical protection, it includes integrated 30 dB feedback isolation, shielding the diode from back-reflections in high-power laser architectures. With an industry-leading 46% electrical-to-optical efficiency and a robust thermal design, this module is the premier choice for Nd-doped laser pumping, surgical aesthetics, and precision laboratory spectroscopy.
