In this week’s Fourier Optics course we shall be looking at diffraction. The central idea is: decompose an arbitrary light distribution in one plane into a sum of plane waves with Fourier transform to solve the Helmholtz equation for light propagation. 🧪 #physics ⚛️ #optics 💡 #iTeachPhysics 🎢

Two mathematical definitions: those of the Fourier transform of a two dimensional function; and that of the inverse Fourier transform.

An international team of scientists, led by Dr. Lukas Bruder from the University of Freiburg, has successfully generated and controlled hybrid electron-photon #quantum states—known as “dressed states”—in helium atoms using intense extreme ultraviolet (EUV) light pulses.

Classically, constructive and destructive interferences are a result of in-phase and out-of-phase wave superposition. But as of quantum theory, every measurement process out to consider the measuring device itself. That's, interferences are defined on the basis of the interaction of light and matter

New pre-print out! Following up on our most recent work, we analyse the nonclassical state from high-harmonic generation. Estimation of the squeezer distribution and Schmidt number further confirm HHG as a promising quantum source of light. arxiv.org/abs/2411.02311
