    And now for my next experiment:
    --An Expert said you can do this with fiber but wtf--
    sure pwi --oh well--

    WTF is right... I think you need to provide a lil more back story for this. Liquid?

    Yeah tequila might work.
    Ok elaboration-- photon mixing.. When you combine red and green, you can see the individual components or red and green if you look closely at the beam. When a dense fog is introduced into the equation (into the beam path), the beam appears yellow or orange (depending on the mix) due to what only I can guess is photon collision or mixing. I'm going to experiment with different liquids and solids or even a tube of fog to see if I can get a pure yellow/ orange output. It was posted in another thread that a piece of fiber-optic cable will do precicely this, but it was not elaborated on. Fiber mixing would be difficult and expensive due to the precision optics and fittings required. Basically what I want to do is red/ green in; yellow out.
    Materials I was thinking about trying:
    Alcohol
    Rhodamine 6G
    Water
    Fog (air/Water mixture)
    lexan
    xenon
    argon
    tequila
    gin
    bourbon

    i will tiptoe out into this with small technical knowledge, o.k.?

    it seems to me that using a liquid or solid ,you would incur large loss.
    even dense fog can easily obscure a lower power laser.

    what about this.
    mylar gels,something thin.
    would it help to use gel colors that are opposite the color wheel from red and green?
    would a specific color gel"pass"more light?

    Interesting idea..
    I realize I'm in for a power-loss but it would be worth it (for me.)

    If I put a R/G beam into a dichro that passes only yellow, I would get zero output, right? I would like to see at least 50% out.


    I was thinking also about using 2 ball lenses to focus the beam to such a tight 'critical mass' that the photons were forced to merge and then re- expand / recollimate the beam.

    Have you measured the size of a photon lately?

    yeah,i can get the size,but for some reason i can't seem to fix it's position

    Light follows paths directly traceable to source, it's why it's hard to block light from getting back to destroy a diode by retroreflection. Same thing makes it hard to make light look like it came from a different source, and is why you can't mix it so easily. A fibre does it by bouncing it around so much that different sources end up looking the same from the other end, on any scale we can see by eye, even after diverging from the fibre end.

    You might not have to mix in a fibre though, one thing single mode fibres can do is get the ends so close together that they look like a single source. That can let you mix beams of arbitrary wavelength and number (up to a point). A cluster of seven fibre ends is one way to get a powerful red laser. Not an easy one though.
