Uncompromising performance

The 1064 nm 20 W Fiber Coupled Diode is a high-power industrial and medical laser module designed for applications that demand high brightness and deep-tissue penetration. Featuring a concentrated 200 µm fiber core, this module provides superior beam quality and power density, making it a critical component for precision surgery and material processing. Engineered for high-efficiency operation, the KA64 series achieves a 50% electrical-to-optical conversion rate, minimizing heat load and maximizing system longevity. The integrated 635 nm visible aiming beam allows for exact targeting in surgical settings, while the high-resolution monitor photodiode (100–2000 µA) provides ultra-stable power tracking. Built with rugged SMA905 termination and a 10 kΩ thermistor, it delivers the consistent, high-intensity 1064 nm output required by top-tier medical and industrial laser systems.
