Unfortunately, I understand completely.
Laser = "laser - an acronym for light amplification by stimulated emission
of radiation"
Laser rework natural light (radiation).
Antennas produce artifical radiation in the result of the electron
oscillations.
To make the oscillations we use different devices.
LC for radio waves, megatrons for microwaves, claystrons for radar waves and
the Halbach array for the light frequency.
The word "laser" is probably common name for the all atificical light
sources.
