Really so cellphones are actually microwave lasers, cool!

  We do actually have microwave lasers, which IIRC predate lasers, called masers. Of course, there is no cellphone equipped with such a thing.

    Masers are cool. My dad worked in an optics lab that used Masers in college and they used Styrofoam for lenses because it's transparent in the microwave spectrum and induces refraction well.
