Dear listers,
 
633nm 5mW HeNe laser LGK 7628-1 went dead on our
LSM 510. The laser has been working for 10years and
most likely >5000 hrs and suddenly stopped producing
a beam.
 
The confocal is off service contract so I am looking for
inexpensive option to self-repair/replace/refurbish the
laser. Core Directors and Managers please share any
related experience. Contacting me off list is fine.
 
I googled a used/refurbished laser of the same model
for $650  (4 month warranty included). Any experience
with such option is greatly appreciated. I project about
1000 hrs laser usage in 2-3 years, and paying the full price
for a new laser would not be cost effective.
 
best,
Arvydas
