Just a quick informal survey,
How many SLA-3500 and SLA-5000 users have had to have their lasers "retuned"
(reorient the laser crystal due to a burnt spot) and if so, how many hours were on the laser when this was done?
The laser power on our SLA-5000 was around 247 mW in March, 1998 (first month of operation). In the past 2 weeks it has dropped down to 210 mW and is slowly dropping. The laser hours are around 1,600.
I'm curious to see what other users are experiencing.
