Hangzhou Brandnew Technology Co., Ltd. is one of China's leading manufacturers and premier suppliers of advanced high power 300w 796nm unmounted laser 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.
High Power 300W 796nm Unmounted Laser Bar
High-power diode laser bars for the most demanding applications. They are extremely reliable, efficient, and durable.
Our semiconductor products are easily assembled using standard soldering methods. 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.
