I would start saving up for a new laser if I were you, but I still have never heard of someone killing their laser due to mode shifting via temperature changes :thinking:
Anything rattling in the head? My first thought was with everyone else: bring it up to a normal temperature and let the laser's temp stabilize. Kind of like how if you bring a screwdriver or hammer inside, the handle gets to a nice temp quickly, while the metal stays cold.
Then, give that a shot with a fresh battery and see if it still mode-hops.
My second thought was the batteries. Less likely because it suddenly decided to dislike your batteries? But, there are many batteries that have the correct voltage when metered on a voltmeter, but just can't put out the amps. Usually, they are china brands, and some china brands are so bad that they are simply trash cells that were picked out of a pile and wrapped up in a pretty wrapper.
My third thought is that a lens has been knocked free from it's "mount." In compact units, the mount usually consists of whatever metal is closest, plus a dab of epoxy. Rattling noise in the head would verify this. the lenses are tiny, and the one that would get knocked loose would probably be about the mass of half of an airsoft pellet, so imagine the feeling and plastic-y sound of half an airsoft pellet in there.
Can you get pics of the now larger dot, and possibly a pic of the dot after shining through a lens to give us a better idea of how much larger your dot is, and to verify for sure whether it is mode hopping?
