You are right, forgot it's the other way around for doping, less for CW rods. I had even chimed into to another thread once pointing out CW rods are lower doped, how could I turn that around! Only reason I was interested in this rod is it has mirrors deposited on the ends for HR and OC. I would flash lamp drive this, already have the HV power supply and flash lamps I need, just need a mount and reflector cavity, to get it to produce the best power output.
I've got a newer edition in hardcover. It is an excellent text with a fair amount of math too. I have been reading it since I got it some months ago. It is also a great reference if you need to look something up quickly, but only after you are familiar with it.
I think most of us initially think the doping would be higher for a flash lamp pumped rod
If a YAG is the same hardness as a sapphire, it is a 9. Quartz is a 7, I think. I used to know these of the top of my head. I am sure Ruby and Sapphire are a 9, though.
So the odds of that rod being glass are nil. Non-zero, but very, very, low.

I agree with everything you said until I got to this line. What rod are you talking about. I have no idea. The information I have came from "Solid-State Laser Engineering", by Walter Koechner. I have a late edition hardcover copy.
