> ** What recoil do you see from a HEL?

Photons have momentum. They don't have mass, but they do have 
momentum, calculated as planck's constant / wavelength (I think 
that's right, ooo my memory is bad today, I think there might be some 
2*Pi factors in there).

A laser shoots out a lot of photons. Conservation of momentum has to 
apply. The laser must therefore recoil.
