Laser light would be more efficient but you would have to know where to point the laser.
Probably something that would need to be "negotiated" with radio communication first to convey specifics of wavelength though.

You can make a laser out of radio waves, there's nothing special about radio waves that prevent you from making a radio frequency laser.

RASER sounds pretty cool too.
