Overview of K940M: 940nm Multi-Mode Laser Diode

The K940M is a high-power, single-emitter, multi-mode OEM laser diode.  This fiber-coupled, 940nm diode laser offers up to 200W of continuous wave (CW) output from a 400-micron core diameter pigtailed fiber optic cable, terminated with a SMA905 connector.  All of the diode lasers utilize proprietary fiber-coupling techniques, resulting in volume products with high efficiency, stability, and superior beam quality. The K940M achieves this by transforming the asymmetric radiation from the laser diode chip into an output fiber with a small core diameter by using special micro-optics, resulting in exceptional brightness.  Additionally, all our laser diodes go through extensive inspection and burn-in procedures at each step of the production process, guarantying reliability, stability, and lifetime.
