OSRAM announced a new green laser diode for pico projectors. The PLT3 520D (520 nm) achieves an "unprecedented high pulse output for direct green laser diodes" of 140 m (at 300 mA) in pulsed mode (50% duty cycle).

OSRAM says it managed to increase the efficiency of its green laser to a typical value of 8%. The PLT3 520D has a diameter of only 3.8 mm.
