Coherent gold plated copper water cooled heat sink for laser diode etc.

Description

This was in a box of items from Coherent. Looks like it was to cool a laser diode.
Not sure what model it was meant to cool. Refer to photo with dimensions to see if it will fit you laser.
You can always remove the alignment pins and configure it for your own use. I would think it's safe to drill other holes that are in line with the existing ones too. Or add a clamp.
Nice and heavy. Weight of heat sink and box, 18 ounces,
I combine ship to keep costs down.
