I have a fully operational LS 800 with a dye module. Now, I am working on a new conversion project that requires a dye laser module and the LS 600 would be a great start. I may blow up some windows and additional sub-components would be welcome as well. This laser will be directly fed and so the whole fiber in/out is not needed. I may replace the cavity mirrors, but the windows and input mirror need to be in good shape as does the whole fluid handling system.
