    Default 6x 405nm diode testing

    got myself a 6x diode from here for some testing -

    http://www.o-like.com/b2b_cpinfo.asp?id=1053







    the results so far - this is with heat sink only NO tec. as you can see from the pic's the thermometer is attached to the top of the diode block

    start -

    145ma
    152mw
    22.5deg's

    30mins

    152mw
    25.2deg's

    1 hour

    152mw
    25.6deg's

    Now i know from previous diode testing that if the mw’s hasnt dropped for a whole hour the diode can handle this power without any problems. So turned it up to 200mw’s.

    180ma
    200mw
    25.6deg's

    1.5hours

    198mw
    27.5deg's


    2.5hours

    197mw
    27.8deg's


    3 hours

    197mw
    28deg's

    will update later

    Awesome test andy. Let us know how it goes. Wouldn't mind building a dual setup with these diodes. Where did you buy your powermeter from?

    Looks like a laserbee.

    Default Lens?

    Is that an acrylic lens? Do you have an AR coated glass lens to test the power output? I'm thinking it could be around 250mW with a glass lens.

    That doesn't matter too much, compared to stability. I am looking forward to more results.

    Laser (the acronym derived from Light Amplification by Stimulated Emissions of Radiation) is a spectacular manifestation of this process. It is a source which emits a kind of light of unrivaled purity and intensity not found in any of the previously known sources of radiation. - Lasers & Non-Linear Optics, B.B. Laud.

    Andy, I reckon you need to invest in a nice desk to work at - every pic from you seems to be taken on the floor!

    Very nice review. Please keep us updated. I am interested in adding 400mW of 405 to my projector.
