It is well known that finite size objects can emit radiation beyond the Planck ( or black body) limit. Is there a good thermodynamic base explanation for this phenomenon?

What are the units of intensity of a laser beam? as an example say Gaussian laser beam. is it W/m2? in some document they have stated this as " irradiance" Then in that case units of W/m2 is ok....

I'm researching light sources and their UV emissions. I'm curious if a 50W, 7500K conventional LED lamp emits any UV light. I found that a 200W tungsten lamp can emit up to 1.5 mW/cm² at 350 nm....
