Compact Blue Sources

Compact blue sources based on frequency doubled lasers. Our approach of intra-cavity frequency doubling in a Vertical External Cavity Surface Emitting Laser is very compact with high efficiency light generation due to high intra-cavity powers and high quality beam profile for coupling to fiber optics and other systems.

A recent development is the first 430nm optically pumped VECSEL seen in the photo below.

Our work in this area has resulted in development of 10-100 mW UV LEDs emitting in the 350-390 nm region (patent application submitted) and the development of 490 nm and 430 nm optically pumped VECSELs, including a demonstration of lasing in electrically injected 860 nm VECSELs (patent application submitted).

More information on VECSELs

We are expanding these new technologies into new projects and commercial partnerships.
