    Default DPSS Laser Mirrors

    I need a mirror set for a DPSS laser I'm building, preferably one for the L-Fold here: http://greyghost.mooo.com/repairfaq/sam/dpss2asm.gif. Anyone have some for sale or trade, or know of a good place to get some mirrors? (Ebay has failed me )

    I bought a surplus lot from a local company here that included a big box full of new optics from CVI for prototyping. The nice thing is that they are all marked with full specs so there is no guessing as to what they are for.

    Considering that drawing came from the infamous Stan Turecki, aka Bob, I'd check that resonator in PSST! software first, for stability criteria. It may be much more of a guideline then a functional system.

    Stan was not known for his honesty, the trail of disgruntled and ripped off customers is long.


    Considering Bob/Stan's past hijinks, that drawing could have been for misleading people just as much as it could be for helping them.

    Also keep in mind the thermal lensing in the rod is wildly different for rods from different makers and using different pumps. You will have to move things around.

    Got all the mirrors here. I just don't have a 25cm, I have 20cm and 30cm, if you have PSST, try modeling them and see if it would work.

    PSST doesn't seem to do V-folds, but modeling a 55cm cavity with a 50cm RoC mirror and 20 cm RoC mirror tells me it is stable.

    What does it say with the 30cm? If that works it would be better as I have a bunch of 30cm and only one 20cm

    Hows $150 + Shipping sound for the 3 mirrors?

    They are all 1/2" diameter 1/4" thick and new in the box (just stuck them in one case for simplicity sake).
