I was gonna say you could use a regular aixis lens to defocus the beam and check if it ever mode hops, but you've probably already figured that out with the loupe.Yup If only I had some sort of matches or something, I could try lighting it!
Divergence, by the way, is excellent - probably around 1mRad. That said, I am pretty sure it stays in TEM00, but I can't be certain; the unit is not focusable.
EDIT: Wow, just tried using a loupe and some black plastic... I got a 589nm that will BURN things. It's set to infinity, so it's not going to burn well there, but when it's focused... it'll burn!
I second the request for more beamshots! Take some in the night sky!
