Scientists have managed to transform a radically different laser concept into a radically different laser reality.

Quote

It’s 30 micrometers long - that’s 30 millionths of a meter - eight micrometers high and has a wavelength of 200 micrometers. This makes the laser considerably smaller than the wavelength of the light it emits - a scientific first.

Is seems to be based on the same general principles that allow cell phones (and other portable wireless communication devices) to use an antenna that is shorter than one-quarter of a wavelength of the frequency it operates at.
