12W Chip on Submount Laser Chip:

The term "COS" in relation to laser diodes typically refers to "Chip on Submount" or "Chip on Substrate." This is a type of packaging or construction method used in the manufacturing of laser diodes. In a COS laser diode, the semiconductor laser chip is directly mounted on a submount or substrate, which then can be integrated into various applications.

BrandnewTech's 12W Chip on Submount (CoS) laser diode delivers up to 12W continuous-wave output power with excellent thermal performance and reliability. Designed for integration into high-demand systems, this compact CoS laser chip is ideal for fiber laser pumping, medical devices, IR illumination, and OEM industrial solutions. Custom submounts and optical coatings available.

✅ 12W output @ 940nm
