Radio Wave Laser: Feasibility & Applications

[jonthebaptist]

I am merely getting curious in thinking about building a radio-wave laser. I'm not seriously pursuing this, but I think it would be cool to build a laser that is ~10km in length. Is anyone aware of any research into this type of monstrosity? Any thoughts about the feasibility or the potential applications?

What do you mean by "radio-wave"?
Are you referring to the frequency?
If so, this is known as a maser (the m is for microwave) and they have been around for even longer than lasers.
