... Go read Artemis Fowl!! The Neutrino weapons have a setting for lasers that throw people back.
Laser ablation could work perhaps... at least on metal targets.
http://en.wikipedia.org/wiki/AblationIt would require an extremely powerful laser to get a high enough ablation level to actually cause concusive force, however.
Lasers (real ones at least) create focused coherent light. The photons of said light do indeed have momentum, but it is miniscule compared to that of a particle of similar energy.
Despite what you see in fiction and / or cartoons or anime, real lasers would not be able "knock something flying"
A beam of neutrinos might be able to do the trick, but that is NOT a laser.
Laser is an acronym for "Light Amplification by Stimulated Emission of Radiation". A neutrino is not a form of light. (Artemis fowl got their terminology wrong on that)
Given that lasers deal with light, I think this would fit better under
than gravity, or under
if you go with ablation.
I could see the laser blinding something... which would be a better (more believable) way to link with the stun mechanic.
If you still like going with
, why not rename it as "Neutrino Beam" or "Neutrino Pulse"?
