    I read back un June that it may be possible to create holograms with 445nm in the single mode at low currents, got excited at the idea of using them.

    What kind of plates did you use?
    Nice to hear your getting back into holography, its amazingly cheap to make a hologram
    today compared to 30 years ago !

    you should stop by the www.holographyforum.org and catch-up on all the things holography

    Talking Wow!

    Do you uniformly get that easy a release from the mold-glass, or are you using any mold release coating? You make it look so easy!

    I am impressed!! That looks so simple!!

    Now, he talks about his formula and that he uses dichromate. I will look for it in these forums.

    THANKS!!
