Doubtful, since rocket exhaust would be pretty hot, and with no surrounding
air it just sprays off and diffuses into the void. That wouldn't leave
enough atoms to ionize.

You would have to take a flouride excimer laser at 150nm. That would be
ultra violet and not visible anymore. One day people might even be able to
build them smaller than the size of three
refrigerators :) (sure would look kind of clumsy on H.E's mech)
