A Resident boffin (with appropriate boffin qualifications) has crunched some numbers, and essentially, the diameter of the wavelength of the whatever of whatever (clearly as you can see I am an expert in the field), by the time it reaches you even a couple of hundred feet up makes it in all essence just an annoyance rather than a danger. Certainly the likelihood of long term damage to your eyes is very remote.
Of course how much it distracts you at the time is another issue.
And lastly, if they manage to mount a laser on the back of a truck and connect it to the local nuclear power supply may mean that the above is irrelevant too.
