Engineers have identified a new way to produce coherent light by sending a shockwave through a crystal lattice. The shockwave forces large groups of atoms in the lattice to move in the same way as it moves through the material. This synchronized movement of the crystals atoms produces coherent light. The wavelength of the coherent light is dependent on the speed at which the shockwave propagates through the material. In the experiment, the researchers measured wavelengths in the range.
This seems cool, especially if they could make it efficient enough to use for tunable lasers in telecommunications.
