Soraa’s InGaN Green Laser Diodes Have Minimal Speckle
The firm’s latest products are ideally suited for >20 lumen pico projectors and the company will display the green and blue laser diodes at CES in Las Vegas Jan 6-9, 2011.
Soraa Inc., a rapidly expanding clean-tech semiconductor company and a manufacturer of green and blue laser diodes, will demonstrate its latest green laser diodes (LDs) which are ideally suited for >20 lumenpico projectors.
The firm, formerly known as Kaai, Inc., says that 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 the green and blue LDs at its private suite at the Consumer Electronics Show in LasVegas 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 picoprojector display generating technologies including LCOS, scanning MEMS mirrors DLP, and other diffractive applications. Soraa’s green LD devices complement the firm’s previously announced blue 450nm LDs, which the company says already exhibit industry best efficiency and power.
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.
Soraa is a rapidly expanding clean-tech company commercializing disruptive, energy saving solutions. Leveraging fundamental semiconductor materials advances, Soraa was founded in 2008 by world renowned semiconductor pioneers Shuji Nakamura, Steven Denbaars and James Speck of University of California, Santa Barbara.
The management team is led by Eric Kim, former executive of Intel and Samsung, and is comprised of commercial laser industry veterans. Soraa is funded by Khosla Ventures and NEA and operates vertically integrated fabrication facilities in California's Silicon Valley and Santa Barbara.
