content: Here's a Coherent medical laser, used for eye procedures. Found this for $50 at the scrap yard along with a 60W CO2 laser.Reading Sam's Laser FAQ, the tube seems to be similar to a Coherent Innova 60, but not quite the same. Since the machine is dead, if anyone has specs for the tube I'd be greatful, as I'm sure we all want to see it run.If anyone wants the tube and can pay for shipping or pick up in the Vancouver, BC area, let me know.Cheers!David

content: Nice video.... I made one myself if you like to watch it (Youtube "Play with Junk")I thought you may be interested in the Novus maintenance manual which I have in PDF format. It's too big to attach here but if you give me another email address, I will send it.Greetings Chris

content: Mikes e stuff: I don't know about the particular laser referred to, but many argon-ion lasers run directly off the mains without an isolation transformer and so just about everything inside the unit is hot relative to the chassis. With the poor efficiency of a 2.5 W argon-ion laser, that'd probably be a big transformer. I recall using a 15 mW unit that drew at least a KW.Cheers,
