Dear flowers,
I ask you whether anyone have recorded a strange laser failure (Ar-15mW,
air-cooled) in the BD instrument (FACSort). It happens almost everyday during
data acquisition. The laser power and current drops to zero and after approx. 1
minute come back to the normal value. Normal values for laser power and current
were OK. Nothing I have tested helps. The laser have 5000 hours which is close
to its lifetime.
My questions:
1) Could overheating be the cause?
2) How one can decide when the laser should be replaced?
Any other suggestions?
