Green Lasers: The Next Innovation in Chip-Based Beams

On a rainy Saturday morning in January 2007, Henry Yang, chancellor of the University of California, Santa Barbara, took an urgent phone call. He excused himself abruptly from a meeting, grabbed his coat and umbrella, and rushed across the windswept U.C.S.B. campus to the Solid State Lighting and Display Center. The research group there included one of us (Nakamura), who had just received the Millennium Technology Prize for creating the first light-emitting diodes (LEDs) that emit bright blue light. Since that breakthrough over a decade earlier, Nakamura had continued his pioneering research on solid-state (semiconductor) lighting, developing green LEDs and the blue laser diodes that are now at the core of modern Blu-ray disc players.


Check out this article that describes advances being made in the development of green laser diodes -- these are green lasers about the size of a pin head, which will enable our PicoP engine to reduce its physical footprint significantly.

I bought my wife a new I pod, it is fantastic for playing music, but viewing pics and such, it sucks! As far as I am concerned this is good for music only. Now,if you guys can get me a laser projector? I will buy one and consider using the I pod for pics and vids.

Thanks for the link to that article. Gives us idealists a reality check that there are real obstacles to progress. But also a reminder that if you put enough smart people to work on a problem, it's amazing what they'll come up with. These are indeed exciting times . . .

KC, frequency doubled green lasers such as those from Corning and OSRAM will be used in PicoP until such a time that diodes (which are much smaller) are readily available.

Here's another story with more about green laser developments: Osram stresses green light on projector lasers.

Thanks,
Ben

I would think that Microvision would have a product that would make this RC Airplane FPV display even better. What a cool concept.
