In the past we had some laser replacements without power supply or 
replaced power supply without laser and it often tuned out that we 
needed a second replacement a few weeks later. Nowadays the laser and 
power supply are replaced together leading to less down time and less 
service visits.

The error message doesn't seem to indicate a problem with the laser, but 
with your AOTF.

Good luck,
