Kaai starts shipping blue laser for display and specialty applications

Kaai Inc of Goleta, CA, USA has started shipping its new blue laser diode product for display and specialty applications, and will also launch the product and give an update on its green laser commercialization at Projection Summit 2010 in Las Vegas, NV (7 June) in the presentation ‘The Emergence of Direct Emitting Green and Blue Semiconductor Lasers for Display Applications’.

A subsidiary of Soraa Inc, Kaai was co-founded in 2008 by nitride-based semiconductor laser pioneers Shuji Nakamura, Steven Denbaars and James Speck, who are professors in the Solid State Lighting & Display Center of University of California, Santa Barbara (UCSB) and had previously developed the first non-polar nitride laser in 2007. The vertically integrated firm aims to commercialize green and blue laser diodes - based on patented and proprietary indium gallium nitride (InGaN) semiconductor technology fabricated on GaN substrates at a facility in Santa Barbara - for consumer, biomedical, defense, and industrial applications.

The new blue laser diode is designed for integration into portable applications such as embedded and companion pico projectors and features 60mW of 445nm single-mode output power in a compact TO-38 package. Kaai says that the laser operates with high efficiency and requires minimal power consumption over a broad temperature range, meeting the demanding requirements of consumer projection displays, defense pointers and illuminators, biomedical instrumentation and therapeutics, as well as industrial imaging applications.
