Saw this interestring photo today and remembered some LPF people asking about the small size of greens on the new pico-projectors.
"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."
It looks to be direct conversion to 532nm Green with one crystal.
