Visual demonstration of the performance of the diffraction grating. The zeroth order transmission refers to light that goes straight through the grating without undergoing diffraction (which should be ...

First experimental observation of matter-wave diffraction in a short-lived electron-positron atom using a graphene-based diffraction grating. (Nanowerk News) One of the discoveries that fundamentally ...

Transient grating (TG) spectroscopy is a time-resolved technique that belongs to the broader family of nonlinear four-wave mixing methods. It is best understood as the time-domain analogue of ...
