COS (Chip on Submount) laser devices are semiconductor laser chips mounted on high-performance submounts to provide improved thermal management, easier integration, and enhanced reliability. They are the most widely adopted chip packaging format in mainland China, with significantly higher industry adoption than C-mount, T-mount, and similar package types.
Our COS products are available in wavelengths ranging from 445 nm to 4587 nm, covering a wide range of power and application requirements. Unless otherwise specified as DFB, all products listed below are FP laser devices.
Browse the COS products below and select the products that match your requirements. Contact us by email to receive detailed datasheets, pricing, and technical support.
