QD Laser developed a quantum-dots based green-laser for pico projectors

QD Laser developed a new green laser, using a quantum-dots laser. They intend this laser to be used for pico projectors. QD laser plans to ship samples in December 2009, and start volume production in 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.
