And, sure enough, it worked and produced a very exciting field. We called the first one the maser, for microwave amplification by stimulated emission of radiation. You had that idea for the maser ...

Bloembergen's maser is used to amplify weak radiations of very short wavelength--for example, microwave radio signals. In use for a year-and-a-half on the Harvard College Observatory's 60-foot ...

The result is an entirely natural microwave laser, or maser, within the hydrogen range which looks extremely similar to that ...
