Your graph ist fort a 5mW Laser....
Quite different story, Idee more powerful lasers are used.
I bought a 20mW from China for some tests...
When switched on it delivered about 30 mW in the first seconds, including infrared parts, which should normaly been filtered out cause the heat can cause additional damage....
50, 100, 200 and more powerful lasers are widely spread.
So your graph may lure into false assumtions.
Flash blindness up to two minutes, leaving a pilot unable to read any instrument can easyly occur up to 3000 feet and higher.....
Been hit myself, luck was, that I was only the Cp-Pilot at the time.
Keep your eyes away if possible!
