I have two GSI Lumonics Lightwriter XL YAG 50W marking laser heads for sale. One laser is complete and was *last known* operational, and therefore contains a complete head: The FIRST Head: General Scanning Galvo Head with 2x Z1910 (GD330T galvos) YAG (1064nm) focusing optics Beam Shutter (the Focusing Element may be automated - not sure because I haven't looked yet) 5 x 70mm CW yag rod Last-known good arc lamp with unknown remaining lifespan Cast iron bed with adjustable mirrors at either end (one full, the other partial) Crystal Technologies 5100-11S water-cooled Q-Switch Module with RF Driver and Power Supply Quantronics Elliptical Lamp-Pump/YAG Gold-Plated, Water Cooled, Arc Lamp/YAG Rod Cavity, with 5x50mm CW yag rod Red Laser helper (brought in through one of the mirrors Note: The first head has not been removed from the complete laser system. The SECOND Head (lower cost because it needs work) is identical to the first but was used as a parts unit and has a few missing pieces as noted below: Missing the guide-tubes between the pump cavity and shutter, and between the shutter and the mirror Possibly missing a crystal or lenses from the shutter module - reluctant to disassemble the first head to compare. Small arc blemish on underside of the cavity lid arc lamp is toast Very Minor cracking of the elliptical cavity holder (this is non-critical - this piece merely holds the reflector around the rod/lamp) The cavity reflector is radially perfectly intact. Axially (at either end) some of the plating has come off but will likely only reduce output by a very minor amount. Again, non-critical. You many have noticed I lost one of the cavity lid screws down the side of the head. It's down in there somewhere. Bonus: Comes with a little bag of flanges and screws The second head has been carefully removed (not severed like some idiots do) from the laser system so that all water conduits, cable assemblies, etc, are still properly terminated with their various DB-15 and other types of connectors. I wish I were capable of testing these - if I was, I would be using them rather than selling them!! In my estimation, and I am not very knowledgeable on lasers per-se but I can get by, I would say that these lasers would make an excellent project for someone who could remove the arc-lamp, replace it with a diffusing rod - something with a mirrored end but sand-blasted along its length, then injected with 808nm laser light from a Diode Pump Source - this would disperse radially from the diffusion rod into the cavity, then into the YAG rod. With a 100W DPSS (selling on ebay right now for $110US), one could pump the yag rod and significantly reduce the cooling capacity required, and if the q-switch and pulse from the QCW DPSS were synchronized, one might just get good quality Q-switched output from these markers. Or, use a CW DPSS input and just let the q-switch driver run normally. Either way, I think either of these heads would make for an excellent laser project for someone who is technical like me, but has more time on their hands. Me, I just want to move on and buy a proper system. Too little time to play the research and fixit game. Note: If you intend to lamp-pump these, I am also selling an ESKI 150-40 HV power supply for driving these lamps. Package weight is probably close to 150lbs for each. Don't trust ebay for shipping quotes. They're all messed up. I am located in Oakville, Ontario, Canada L6H 4K8. Please quote your own shipping to get a preliminary estimate for shipping costs, then if you're prepared to purchase, we can work out a proper shipping quote. I welcome any inquiries. Thank you for your interest. Torin...
