Dear List Members,

We have a fairly new Leica SP5 system (15 months old) that has a Lasos multi-line argon laser, part number LGK 7872 ML05, which now has failed for the second time within a year.  The error appears if we turn the total power slider to 30% or more, in which case the laser starts to "stutter" (i.e. cuts out randomly during scanning) that produces randomly distributed blank lines and bands in the acquired image.  If we then move the power slider back to below 30%, the laser performance returns to normal. Upon the first appearance of this error, Leica simply replaced the head and the power supply, but now the same error appeared again, making us more than suspicious that this is a common form of failure for this laser in the Leica system.

  Did anyone experience the same or similar problem?  If so, how did you resolve it?  Was it laser specific, manufacturer related or Leica related?

  Any information will be much appreciated!  Thank you very much,

 

Zoltan
