Soraa demonstrates 4 watt blue laser diode for bulb-free projection displays

Company to present results at Photonics West conference in San Francisco Jan 26, 2011

FREMONT, CA | JANUARY 26, 2011

Soraa Inc., (formerly Kaai, Inc.), a rapidly expanding clean-tech semiconductor company and world leader in commercialization of green and blue laser diodes (LDs), announced today the demonstration of high power 4 watt blue laser diodes at 450 nm, the highest power blue laser reported to date from a monolithic chip. These devices are designed to enable >500 lumen, bulb-free projection displays with dramatically reduced size, weight, and power consumption compared to conventional bulb-based projectors used in venues such as boardrooms, education, home theater, and cinema. The company will present its latest results at the Photonics West conference in San Francisco, CA on January 26, 2011.

Additionally, Soraa will present results of 750 mW single mode blue laser diodes, the highest single mode power reported to date. These laser diodes operate with single spatial mode and multi spectral mode and are designed for smaller format display applications such as micro projectors and pico projectors. The devices can be directly modulated at high speeds required for high resolution displays with minimal speckle. Soraa’s LDs are designed to be compatible with all available display generating technologies including LCOS, scanning MEMS mirrors, DLP, and other diffractive approaches. These blue LD devices complement Soraa’s previously announced green LDs. [SEE PRESS RELEASE JAN 5, 2011.]

Soraa's LDs are based on InGaN semiconductor technology and are fabricated on innovative nonpolar and semipolar GaN substrates. Soraa’s 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.
