HSV Technologies Inc is developing a "weapon that uses ultraviolet laser
beams to harmlessly immobilize people and animals at a distance : the
Phaser-like device uses two beams of UV radiation to ionize paths in the air
along which electrical current is conducted"
http://www.hsvt.org/

Do you think the ionized path in the air could be used to carry HF currents?
With strong laser beams -if they don't diverge too quickly- this would lead
to "virtual" very long wire antennas easy to erect!
