Here at Kodak we have had a SLA 350 installed since June of 1996. The laser
has been very stable and is the original. I'm replying to this note from home
so I can't tell you what the logged hours are but if you would like to know I
can pass that information on to you. I can tell you that in that same period
we have gone through 3 SLA 250 lasers (40 Mw) and we're on our second SLA 500
laser (400 Mw).
