    Default New Mits 1.8W 638nm

    Probably be a while before we see these in the wild and who knows how bad the divergence will be but great to see higher power 638nm diodes being announced.

    Emitter size? Divergence? Surely multi-mode....

    Dont know but im guessing beam divergence/size would be like the 9mm NDB7A75 3.5W 445nm diode or even worse, just guessing
    But it could be that if cooled with tec, should see a massive power gain like those G71/P73, also guessing :P
    This would be awesome for Sir " Planters " Lab to do test on these diode if they become available

    Awesome! Too bad they're waiting until 2016 for a production run :/

    Just searched the web and found this...Mitsubishi 638nm Red laser 1800mW 1.8W.
    No idea if it's legit or not?

    EDIT: Just found another site that has some graphs.

    I just checked out your link and looked around, off topic of the thread but HOLY HELL $7,800 for 60mW: http://www.beamq.com/488nm-laser-diode-60mw-p-723.html <-- definitely would need a LasOrb!

    Back on topic, considering the output power and wavelength, $295 seems reasonable. Very curious to see some beam profile pics NF/FF. No doubt it is going to be a fat beam with a nasty fast axis. C'mon Jordan, man up and give us some tests!
    Those who fail to grasp art are the ones who criticize it.

    There are several good things to conclude from reading a bit about this.
    1. The curves shows a linear efficiency in mW up to 1800 at 25deg. How much further we will be able to push the diode before the curve starts to drop is an open but exiting question.
    2. Mistubishi states:
    Future Development
    Going forward, Mitsubishi Electric plans to enhance its new LD’s high-power, low-consumption characteristics, aiming at a commercial launch in the
    fiscal year ending in March 2016, at which time laser light sources for projectors are expected to take off.
    3. Laserpowered porjectors in large numbers, shoud give reasonable prices of these diodes within a couple of years.

    I only hope these are usable as a diecent lightsource in a projector.

    Here's the link to the BeamQ page including pictures

    2.7A operating current, looks like we're going to need some bigger drivers soon.

    You are using Bonetti's defense against me, ah?

    I thought it fitting, considering the rocky terrain.
