Kaai demonstrates 523 nm CW green laser diode

Jan. 14, 2010
Kaai, Inc. (Goleta, CA), a company on the leading edge in commercializing green and blue laser diodes, has demonstrated green laser diodes emitting at 523 nm, the longest continuous-wave (CW) green laser diode emission reported to date (note: these are true green laser diodes, unlike green laser pointers, which are frequency-doubled solid-state lasers pumped by IR laser diodes).

Kaai, Inc. (Goleta, CA), a company on the leading edge in commercializing green and blue laser diodes, has demonstrated green laser diodes emitting at 523 nm, the longest continuous-wave (CW) green laser-diode emission reported to date (note: these are true green laser diodes, unlike green laser pointers, which are frequency-doubled solid-state lasers pumped by IR laser diodes). Kaai displayed green and blue laser diodes last week at its private suite at the 2010 Consumer Electronics Show (Las Vegas, NV).

Kaai's lasers are based on indium gallium nitride (InGaN) semiconductor technology and are fabricated on innovative nonpolar and semipolar GaN substrates. Direct diode green lasers offer dramatic improvements in size, weight, and cost over conventional gas or solid-state lasers (such as conventional green laser pointers) and enable a variety of new applications in consumer projection displays, defense pointers and illuminators, biomedical instrumentation and therapeutics, and industrial-imaging applications.

Kaai was founded by world renowned semiconductor laser pioneers Shuji Nakamura, Steven Denbaars, and James Speck of University of California, Santa Barbara. The management team is led by Richard Craig and is made up of commercial laser-industry veterans. Kaai is vertically integrated and operates a laser-diode fabrication facility in Santa Barbara, CA.
