    Laser Warning Wanted Coherent Compass 315m or similar for Holography. In UK

    Hello

    I'm looking for a laser for holography(green). Preferably one with a long coherence length and reasonable power, >75mw. Something along the lines of a Coherent Compass 315 or similar.
    I'm based in the UK and would like to buy local or Europe if I can as the import duty and VAT from the USA etc works out quite expensive. That said I am open to anything at the right price.


    Kind Regards

    Hi Grayham

    Your best bet is to contact any of the following...

    Dave Battin
    Phil Bergeron
    Sam Goldwasser

    All the above are in the States though. Failing that keep an eye out on eBay, C315m's do pop up from time to time.

    Cheers

    I have two of these that I have been wanting to sell one of them. One is complete with the coherent driver, small custom made heat sink and
    self start dongle. It will easily output 100mw. single mode. I can sell this laser for $1000.00.
    The second laser is also a 315m-100, just the bare laser which will also output a 100mw beam. No driver is included. This laser was modified a very
    long time ago and the "Profile" circuit board has been removed. No damage was done to the hermetic seals in this drastic laser surgery. I used it
    in a previous projector using two wavelength electronic temperature controllers and a 2A laser driver. It outputs a very nice beam I can sell this one for $600.00
    I will ship free to US destinations, and actual cost to international destinations.

    Hi Jem

    I am currently talking to Phil Bergeron and I have messaged Dave Battin via Facebook but have not had a response just yet.
    I am hoping for something closer to home but from what I have read I cant go wrong with the contacts you suggested.

    Thank you & Kind Regards

    Graham...

    $1000 is a good price for a C315m with driver and autostart dongle. You could perhaps do to know the exact power output and what the pump diode current is set to. This will give an indication as to the health of the pump diode.

    I'd perhaps be inclined to have it shipped without the heatsink as it's no good for holography with a fan fitted (unless it's in the room next door ;-)). You can easily find a suitable heatsink to mount it on over here in the UK.

    Cheers

    Hi Jem

    I spoke to Laserbiker via PM and the 100mw lock light comes on as does 112mw if need be. $1000 is a good price but I do have to factor in roughly $300 dollars shipping, duty vat ect. Plus a PSU and heat sink. I have spoken to Laser biker and I am going to wait a week and see if anything closer to home turns up.

    Thanks for your input it is useful

    Kind Regards

    The 315M-100 for $1K is a good deal even with the $300 added on for pond skipping. As I told you we charge $1,500 for tested SLM healthy basic systems. Best of luck, Phil and Sam
