Probably the diode failing, but you could check the lens is clean and straight.

lens clean

If the laser diode is defective, repair is possible ?

I have the same issue with my 3000mw laser as well. Any updates on corrective measures?

It is possible but to do it correctly you need some test equipment that most people don't have. Laser power meter and bench power supply with stable voltage and current limiting capabilities.

could also be a cracked lens.  I had 2 fail due to moisture on the lens before I figured out what was causing it.
