2011 International CES, FREMONT, USA: Soraa Inc., (formerly Kaai Inc.,) a rapidly expanding clean-tech semiconductor company and world leader in commercialization of green and blue laser diodes, announced the demonstration of green laser diodes (LDs) which are ideally suited for >20 lumen pico projectors.
These direct emitting green lasers have produced images which exhibit substantially reduced speckle compared to conventional green lasers based on second harmonic generation. The company will display green and blue LDs at its private suite at the Consumer Electronics Show in Las Vegas, Nevada January 6-9, 2011.
Soraa’s green LDs output more than 75 milliwatt of continuous wave power in the 520-525nm range, are single spatial mode and multi spectral mode. The devices can be directly modulated at high speeds required for high-resolution displays with minimal speckle. Soraa’s LDs are well suited for all pico projector display generating technologies including LCOS, scanning MEMS mirrors DLP, and other diffractive approaches. Soraa’s green LD devices complement Soraa’s previously announced blue 450nm LDs which already exhibit industry best efficiency and power.
Soraa’s LDs are based on InGaN semiconductor technology and are fabricated on innovative non-polar and semi-polar 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.
