Ok, so i have this circuit board which has a laser diode soldered on it. The laser diode itself has a heatsink on which is glued. As far as i know acetone can dissolve almost any glue. So the question is, can i put some acetone on the glue to dissolve it or is this going to damage the laser diode?

This might work, the only risk is that the acetone might dissolve the glue holding the diode window in place.

Can you protect the diode with something, like heat shrink tubing while you use the acetone? Then, cut it off when done.

Can you post a picture of it?
If this is an exposed die style of diode (open can or chip), acetone will destroy either the facet or potentially the die itself.
