In a development that will be welcomed by those awaiting the advent of high-brightness pico-projectors, Germany’s Osram Opto Semiconductors (Osram OS) has launched its first diode lasers to emit directly in the green region of the spectrum.The commercial arrival of the lasers will be welcome news for the likes of US-based MicroVision, which is at the forefront of pico-projector technology development but has struggled financially – partly as a result of delays in the development of direct green emitters, and the high cost of those that are available. The company’s VP of research and development Dale Zimmerman told optics.org last month:
“We believe direct-diode green lasers are finally here for real. We are confident that as volume expands we'll see the pricing of the diodes come down dramatically, along with further improvements in efficiency, and anticipate that red, blue and green direct-diode lasers will be broadly available.”
