Up for sale is one lovely Coherent Sapphire OPSL, 20mW@488 nm. Sam's Laser FAQ has the manual for this laser here, and Coherent has a datasheet with specs here.
Post offers here or PM me. It's a nice laser, and a great way to get the 488nm argon wavelength without the ridiculous power draw of a small argon-ion laser. It's also controllable via RS232.
I'll also take trades of interesting lasers, preferably big green ones (in the unlikely case that one of you has a Laserscope lying around that you'd like to get rid of ).
