QD Laser Inc developed a green laser device using a quantum dot laser in collaboration with the Institute for Nano Quantum Information Electronics at the University of Tokyo.

It is intended for use as a light source for pico projectors. QD Laser plans to ship samples in December 2009 and start volume production in the autumn of 2010.

The laser device produces green laser light with a wavelength of 532nm by changing the wavelength of laser light that is emitted from a quantum dot laser and has a wavelength of 1,064nm with SHG (second harmonic generation) devices.

The new green laser device features a wide operating temperature range (up to 60°C without cooling), resulting in lower power consumption. It operates at a voltage of 2V, and its wavelength can be modulated at 500MHz or higher. It is sealed in the general-purpose package "TO-56" with a diameter of 5.6mm.

The laser device is scheduled to be exhibited at CEATEC JAPAN 2009, which will run from Oct 6 to 10, 2009, at Makuhari Messe in Chiba Prefecture, Japan.
