    Default Mistubishi ML229U7 red laser diode

    a quick search turned up with nothing, so i have to ask

    has anybody worked with this one? http://www.aliexpress.com/store/prod...578477257.html

    is it multimode? any horrible beam specs or something usable?

    Hi Lanek,

    could they be the same as http://cgi.ebay.fr/ws/eBayISAPI.dll?...#ht_3662wt_946 ???


    If yes, they are single mode ( look at the beam divergences , 9° and 19°)

    180mW @ 260mA,

    they have exactly the same efficiency as Opnext HL63133DG 170mW diodes

    After a quick research,

    here is what I found (Mitsubishi RED laser diode available in june 2012)

    Attachment 33346


    Conclusion : this is not a Mitsu diode

    It is definately not this one, as the one i am taling about is a to38 can (3,8mm diode)
    It looks promising, maybe i get around to buying a couple. I have no means to test for wavelength, just some 660 and 640 diodes and some cheap diffraction gratings... ok, maybe i have a means to test for wavelength

    I think ML229U7 is the name of DVD sled or something else.Iirc i´ve seen something on a chinese webpage that shows a DVD sled but it says 250mw 648-660nm.

    the diode is the same as the one on the groupbuy from LPF :

    So if it is this diode, it can be drived at 3X rated current, max 4X

    (look at the video page 2, diode is runned at 1.1A for a few seconds )

    If this is a 650-660nm diode with plenty of SINGLE MODE power and one that's tough enough, that's promising enough.

    I think a lot of us will want some replacement for the dreadful LPC-826 diodes which tend to drop like flies... this one looks a lot more user-friendly. Also, with the price of these in the LPF group buy, I guess we can throw the long open cans in the bin.

    Having an 1W dual 660 with just two of these diodes and a cube, now THAT's totally worth it. As far as the well-known 'case negative' issue is concerned, somebody has a brilliant solution here:

    Will these go in a Dave's clamp down diode mount or is there some trick to get them properly seated with 3,8mm cans?

    Sounds easy enough to me. Two of these diodes, two mounts, a Flexmount, PBS, Flexmod P3 at 800 milliamps and presto -- a full Watt of 660.

    Thanks for the info.
    But why do you advertise it as a 640-648nm diode when it is a darker 660nm diode? Or is it not?
