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 ...

Researchers at ETH Zurich have developed a method for the production of wavy surfaces with nanometer precision. In the future this method could be used, for instance, to make optical components for ...

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 ...

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 ...
