OK, let's see what happens with their most wicked laser. I see the Extreme
Phoenix with a power rating of 500mW.

Their most powerful one is rated at less than 100mw. They claim to use a
500mw diode but the actual output is around 90mw max.

Your 500 mW laser has a power of about .25 mW/cm^2 at 1 km.

Make that .05mw.
