We have a laser with over two years on the lamp. I know they
are not cheap. I would worry about it when it burns out. I am not
sure what make ours is but the Rep was in today to have a look at
ours and he said that everything looked good.
I hate to sound pessimistic, but if you wait until the lamp burns
out, you run the risk of damaging the delicate gold plating that the
lamp is housed in due to the lamp exploding. This can get very
expensive. It's much better to replace the lamp per Rofins
