Green light has a special importance in RGB applications because the human eye is most sensitive in the green spectral range. The brighter the green laser shines on a surface, the brighter and stronger the projected image appears to the viewer. Osram’s PLT3 520D green single-mode laser offers 140mW at 300mA in pulsed mode (50% duty cycle), whereas the limit so far for these components was 80mW. A further advantage of the diode is its compact and space-saving TO38 metal housing with a diameter of only 3.8 mm. The laser diode at 520nm has been specially developed for laser projection applications that use a MEMS scanner as the image encoder. Thanks to these improvements, it is now possible to turn a smartphone into a small cinema projector, expanding the small display several times over.
