Uncompromising performance

The 445 nm 200 W High Power Fiber Coupled Blue Laser is a revolutionary light source designed specifically for the processing of highly reflective materials. Operating in the visible blue spectrum, this module provides unrivaled absorption rates in non-ferrous metals like copper and gold, enabling spatter-free, high-quality welding and additive manufacturing that infrared lasers cannot achieve. Delivering a potent 200 W of continuous-wave output through a high-brightness 105 µm fiber core, the K445 series represents a masterpiece of opto-electronic integration. The system utilizes a multi-module architecture for maximum stability and features an integrated visible aiming beam for precise targeting. Engineered for heavy industrial environments, this water-cooled module includes built-in thermal tracking (10 kΩ thermistor) to ensure absolute diode protection during high-duty cycle operations. With a standard HP-SMA905 technical interface, it is the premier choice for EV battery manufacturing, 3D printing (SLM), and advanced scientific research.
