I got a new laser module to engrave anodized aluminium with,
one with 10W output (40W in it says), NEJE E40.
( https://neje.shop/products/e40 , this one; I had a 5W
output of theirs before that which did not have the power
to engrave the plates I had the most of, was good for those
I had run out of of course).
It worked fine for a few hours of tests then it lost most
of its power. I measured the consumption, it is about 40W
(on a test setup, not while engraving on the machine).
Do laser LEDs fail like this? Just lose output power while
consuming as usual?
I am sort of furious as this was nothing I could not do
without, just wasted time on it. May be some day I'll waste
some more time replacing the LEDs etc. but not today,
may be not this year...

Yes. It’s usually facet damage or dislocations getting into the active area.
I am sort of furious as this was nothing I could not doI doubt you could buy parts for that price.

Insufficient heatsinking is one way that they end up junked

It could just be bad luck. Infant mortality in these devices seems to be
a bit of an issue - a bit like with filament lamps of old if it survives
the first 10 hours from first use then it should be OK for 1000+ hours.
