High-harmonic generation (HHG) is a nonlinear optical phenomenon through which high harmonics of an intense laser beam are generated in a target material, typically a gas. Physicists have been studying HHG in atomic gases ...
Terahertz radiation, whose wavelengths lie between those of microwaves and visible light, can penetrate many nonmetallic materials and detect signatures of certain molecules. These handy qualities could lend themselves to ...
