Soraa demonstrating high-power blue lasers in desktop projector at CES

In its private suite at the Consumer Electronics Show (CES 2012) in Las Vegas, Nevada this week (10-13 January), Soraa Inc of Fremont, CA, USA, which is commercializing nitride-based green and blue LEDs and laser diodes for application in general illumination and projection display, is demonstrating high-power blue laser diodes (LDs) integrated into a desktop projector. The firm reckons that this represents the world’s first desktop projector demonstration based on high-power nonpolar-semipolar laser diode technology.

Soraa has demonstrated output of more than 2W from a blue laser diode, and more than 4W from a blue laser array with continuous-wave power in multi spatial mode and multi spectral mode. At green wavelengths, Soraa has demonstrated more than 100mW of continuous-wave power in single spatial mode and multi spectral mode. The devices can be directly modulated at the high speeds required for high-resolution displays with minimal speckle.

Soraa’s laser diodes are based on indium gallium nitride (InGaN) technology and are fabricated on nonpolar and semipolar GaN substrates. The firm claims that its direct-diode green and blue lasers offer improvements in performance, size, weight and cost over conventional gas or solid-state lasers for consumer projection displays, defense pointers and illuminators, biomedical instrumentation and therapeutics, and industrial imaging applications.
