There were a few people here bringing attention to a possibility to kill a laser even with a very short pulse. Suddenly, I found a Wikipedia page about it: Catastrophic optical damage. Enjoy.

The article still refers to heat as the final reason of mirror death, but the thing is about local thermal runaway. It somewhat reminded me of a secondary breakdown phenomenon in bipolar transistors (BJTs).
