If you turn the pot too far and the diode dims can you turn it back to where it was brightest again?
Maybe, with DPSS lasers the dimming can be caused by an excess of pump power, it doesn't necessarily mean that the diode is dying. Diodes also sometimes lower in power if you drive them too hard, before they die.
It's also possible that it died or was damaged and turning it down won't bring power back up.
