In a rare invention, the researchers at Princeton University have successfully developed a tiny microwave laser or “maser”, which is as small as a rice grain, using quantum dots.

The maser is equipped with quantum dots that are artificial atoms. In greater depth, quantum dots are the small particles of light-emitting nanocrystals that have the ability to absorb light from one wavelength and then convert it to extremely saturated light at certain wavelengths.
