    Oh yeah and they loop the fiber into a coil to conserve space i guess--
    I suppose it doesnt mind being looped, being a light conduit..
    Ill try to find the opto-schematic i found a few days ago and post it>

    I believe retail on the tapered fiber is only about $3-5k... If you add a nice surplus pump system for $20k, then you could build this (to professional specs) at home for $25k-ish... If you're not picky about the output, then I'd guess homebuilt for $10k...

    umm...
    as sexy as it looks through a diffraction grating...

    How the fuck would you modulate that ? I mean, with current technologies, how would you achieve pcaom like performance, with access to all of the wavelengths...

    It would be a very nice income for a hobby.
    I wonder what the component cost actually is?

    Ailii--I guess you'd do the same way as a high power white-light mixed gas laser. Prism and pick? The only thing is I dont know if this is a CW or pulsed. Maybe not ok for high speed graphics.
    Yadda--Price quote from Sumita's fiber:
    Thank you very much for your inquiry of our Downconversion Fiber.

    360usd for their type- not too bad, maybe more $$for others.

    More info, but I cant seem to fcking find the type of pump laser and power goes with which fiber. This is alot of research. Oh well , back to work.

    Here's an interesting one..



    Thulium-doped upconversion fiber laser

    Pump wavelength: 1120 nm; Laser wavelength: 482 nm; Output power: up to 400 mW

    And the cost of this little beauty...............

    How much power is lost through the walls of the fibre?

    Don't know,
    Don't know and..
    Don't know.
    I wish I knew.
    I wish I was an optical engineer so I'd know what the hell I was reading in all these pages on optical fibers and upconverting and downconverting. This is isn't going to be easy. Oh, and that little beauty-- probably have to
    DIY.. I doubt if it comes pre-assembled . That would just add to the cost I'm sure anyway. I now know that a Ti:sapphire pump laser is definately out $$$..
    learning as we go...
    Is there a fiber expert in the house???
    Added info 3/6:---------------
    I believe this is a university project.
    That pic is out of their gallery:

    It may a one-of-a-kind:/
