Like I said, it was an educated guess as your spectrometer isn't calibrated. I do see what you are talking about in the pump energy necessary to get the dye to lase. I have been reading Koechner's book in order to learn enough to build a ruby laser. Of course, I am learning much more than just what is needed to build that one laser. I have learned a great deal about Nd:YAG lasers in the process. And a whole lot of information I may never use again.
