Um, The science guys and one of the manufacturers are hopefully jointly bringing a Spiricon CCD based M2 beam quality measuring system this year that should be open to anybody if we can attenuate the beam enough to protect the CCD. . Its the one with the automated sliding optical rail for measuring divergence and M Squared quality factor.

I had a single axis "BeamScan" there last year that was open to anyone provided we could attenuate the beam enough to scan it. It got used a little.
I'll bring it again, but with a real Xy and Spin mount this time and multiple ND high power filters I just bought.

That takes the "gripe" from the science guys to the artists who will hopefully dig in to learning what the data means.

But measuring diode stacks is a bit on the poorly defined side still. The international standard is a work in progress, so I'm told. Trust me, watching the stacked beam profile change massively with diode modulation on multiple diode setups is very interesting.
