What all can a laser lase and make "radioactive"?

Ha, I was just going along with the sub-forum title! lol

That is pretty interesting, thanks for sharing!

I've got a couple small bits of uranium glass on my Ebay watchlist at 0 bids. If no one bids I'll swoop in, but would like to get some various small bits for lasing. And showing off of course....

You need a Ur marble?

It glows yellow with a 405 nM but no Geiger counter clicks.

Well, not really but that doesn't mean I'm not interested!

The uranium/vaseline glass I was watching evidently is more popular than I imagined, it went from 0 bids up to 20+ in the last couple hours.
I'd like to get a few small trinkets fun to lase.
