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 ...

Ever since the first observation of high-order harmonics generation (HHG) 1,2,3,4 using ultrashort ultraviolet (UV) and infrared (IR) laser pulses, this extreme nonlinear upconversion phenomenon has ...

The scanning interference field exposure technique is an effective method to fabricate holographic diffraction grating with meter-level size and nano-level precision. The main problems of fabricating ...

This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...
