We were going to build a laser, but found two working surgical CO2 lasers, each with articulated arms. The smaller of the two is Coherent 30 watt with hand piece, and is a sealed beam, with sealed liquid cooling system. Once we got it home, it wasn't junk...it works!

The larger is flowing gas 60 watt CO2, with instrument panel showing approx. 300 hours on it. It has sealed liquid cooling system as well as the vacuum pump. It appears to be almost new, just doesn't have the pressurized tank, or such external parts. You don't want to know how little it cost us...less than the price of a new transformer for it...

Originally, we were going to use them as scrap and build off of the parts....great transformers, sealed liquid coolant system with pumps, integrated He/Ne pointer laser, articulated arms, and very robust build for a rack, associated with operating room equipment. We were going to use the parts and adapt the "newly functioning" lasers for light cutting duty and engraving, on two machines we were building or re-fitting.

Once we found that the Coherent actually worked, we decided to use as is. since it is a very nice, compact mount for all the nec. equipment. We wanted to gather the technical manuals so that we could tell those helping, just what kind of laser tubes were involved and exactly what kind of electronics is in the package. There is even a computer port for the Cooper flowing gas laser....to what for what?

Therein is the rub....we are unable to find schematics and technical manuals.

So, does anyone out there familiar with these two instruments have any source for technical manuals? Neither Coherent nor Lumenis has them (at least they are not willing to dig in the graveyard files for unsupported equipment.....) ??

It seems a waste to throw out all the circuits ( with all kinds of power settings, pulse settings, and so forth) and go with what is essentially a home brewed laser!!??

Sorry to not be able to provide all the documentation before we opened up the thread...maybe there isn't any interest in what appears to us to be a good place for some basic laser/cnc learning...?? Lots of good, basic learning to be discussed in the forum as we convert.

Initial equipment is on hand is an Isel cast off engraver (somebody thought it to be junk!) with servo motors and 4 axis DeskCNC system....up and running with rotary now and hand piece for laser ported for pressure air. Other things are being built or converted.

But we are definitely newbies to all of this!!! Help!!! Maybe we can learn together? Does anyone have a source for technical information for these lasers? Or do we just open it up to you experts here, and start throwing out parts ??
