Only 20 watts...

I noticed in this picture you can see a divergence.

Is this some kind of wobble or modulation over the obviously
long exposure time or the Gaussian character of the beam.

Incidently, whats the beam's divergence angle and waist size. I'm just curious about what the spot size is at the sodium layer.

Incidently, what is the energy of the K2 LGS?
