    Call Coherent Scientific Product Line service hotline and provide serial and model number.. IF they still have it...

    I'll see, but I don think I have it. HIS or Mary's laser?
    Mary still had the manual for the similar beast. She also spent a week at the factory and had a friend that serviced those.

    That was my first call. Nope no info. Itís his sohio laser. There are three actually. Really just need to know the dumper and what and how it works. Rest looks pretty easy to figure.

    AO or EO dumper?

    Either way its a hunk of quartz at Brewster' angle in the cavity.

    You either adjust the cavity length to match the dumper frequency or tune the dumper frequency to match the cavity length.

    The dumper by definition deflects the pulse out of the cavity, either by a actual beam deflection or by rotating the polarization.

    Is it already aligned and lasing ?

    Try Bob Arkin a Holospectra.

    Radient Dyes makes the nozzles, which wear out. Thy probably know a bit.

    Take look at the 699 and 899 manuals, which ARE online.
