> imagine a laser at typical radio wavelengths

Huh?

Radios are Kilo/Mega/Gigahertz.

Light is Terahertz.

Okay, sorry, "electromagnetic radiation amplified and collimated in the same manner as a laser does to visible light". Better?

Like beamforming, or something more extreme like a maser?

As an aside, the Maser wikipedia article is a bit incorrect.

> The laser works by the same principle as the maser, but produces higher frequency coherent radiation at visible wavelengths.

There are plenty of lasers in the non-visible spectrum, I use IR lasers all the time.

A maser's what I had in mind, but either would likely work reasonably well.
