The 940 nm 10 W Fiber Coupled Diode Laser is a high-efficiency source designed for precision-demanding industrial and scientific applications. With an industry-leading 52% electrical-to-optical conversion rate, the K940 series is engineered to provide maximum power throughput while significantly reducing the thermal footprint and cooling requirements of the system. Delivering a stable 10 W output through a precision 105 µm fiber core, this module provides exceptional brightness and beam quality. For enhanced operational safety, it features integrated 30 dB feedback isolation (1400 nm–1600 nm), protecting the diode from back-reflections in complex optical setups. Housed in a robust, compact industrial package, it is the premier choice for laser pumping, CATV networks, and LIDAR systems where high stability and long-term reliability are non-negotiable.
