I have a Crylas FTSS-Q3 532 nm pulse laser (http://www.crylas.de/productsheets/FDSS_532-Q.pdf) for sale. This laser can be used for cell ablation, axon cutting, etc., as well as laser capture and material processing. It only has about 2000 hrs of use (I think the MTTF is about 100,000 hrs) so it should have a long life ahead of it. I also have a Glan-Thompson polarizer for beam attenuation and assorted lenses and hardware for a beam expander. Original cost was about 11K for laser. Contact me directly if you are interested. bastiani@bioscience.utah.edu
