As for ensuring the efficient transfer of beam energy to air… the people working on microwave electrothermal thrusters have already solved this by using focused energy to create a small spot of plasma in the propellant flow.
Yeah, microwave electrothermal thrusters use a propellant, like water; in space we’d still need a propellant, but this is a jet. i’d prefer to avoid noxious exhaust products, so maybe not raise it to plasma temperature.
of course there’s science to do, to make this go. i dont have all the answers, but tuning and focusing the beam seems to be the key
