Hangzhou Brandnew Technology Co., Ltd. is one of China's leading manufacturers and premier suppliers of advanced 600w 940nm unmounted diode bar. Operating a state-of-the-art factory, we specialize in the entire production spectrum—from high-performance chips, TO/F/C Mounts, COS, and MCC bars, to robust stacks and advanced fiber-coupled solutions.
600W 940nm Unmounted Diode Bar
Overview：
High-power, 940nm, unmounted diode laser bar, with 600W of QCW output power, designed for the most demanding applications.
They are extremely reliable, efficient, and durable.
The 940nm wavelength is widely used for applications such as fiber optic pumping, laser welding, and medical treatments, ensuring optimal performance with high stability.
These chips are designed for high optical-to-electrical efficiency, minimizing power loss and optimizing overall energy usage.
Our semiconductor products are easily assembled using standard soldering methods.
The material supports both soft solder (indium) and hard solder (gold/tin).
We deliver our laser bars to you with emitter structures separated on the p-side as standard.
On request, we can also produce bars with continuous p-side metallization and adapted facet coatings, using low AR coatings for the assembly of external resonators.
