Dear all, I managed to break off a prism in the prism beam expander of a Quanta-Ray PDL-3 dye laser. When trying to glue it back on, I managed to break off two more. I guess the glue was quite old. Nonetheless, I feel so stupid.... Did that happen to someone else before? What is the procedure to get them back on AND have a well aligned beam expander? I hope the get this otherwise so well working laser back in operation.
