Next on the block is my >2W Melles Griot DPSS. The head is model 58-GSD-309 made in Feb 2001 and the PSU is 58-PSM-281 made in Aug 2000. This had a new pump diode installed by Once Stop Laser Shop a couple of years ago and I've put about 100 hours on it since then. It's making about 2.4W raw (dual beam) and 2.2W with the beam expander / combiner installed. I'll warranty it to do >2W for 90 days. Grab it now for $2000 plus shipping before I take pictures and post it on eBay
