Resonant Interaction of Modulation-correlated Quantum Electron Wavepackets with Bound Electron States

Posted by klaurent Caltech

Kavli Affiliate: Amnon Yariv | First 5 Authors: Avraham Gover, Bin Zhang, Du Ran, Reuven Ianconescu, Aharon Friedman | Summary: Free-Electron Bound-Electron Resonant Interaction (FEBERI) is the resonant inelastic interaction of periodically density-bunched free electrons with a quantum two level system. We present a comprehensive relativistic quantum mechanical theory for this interaction in a model […]

Topology optimized multi-functional mechanically reconfigurable meta-optics studied at microwave frequencies

Posted by klaurent Caltech

Kavli Affiliate: Andrei Faraon | First 5 Authors: Conner Ballew, Gregory Roberts, Philip Camayd-Muñoz, Maximilien F Debbas, Andrei Faraon | Summary: Metasurfaces advanced the field of optics by reducing the thickness of optical components and merging multiple functionalities into a single layer device. However, this generally comes with a reduction in performance, especially for multifunctional […]

Diffusing wave spectroscopy: a unified treatment on temporal sampling and speckle ensemble methods

Posted by klaurent Caltech

Kavli Affiliate: Changhuei Yang | First 5 Authors: Jian Xu, Ali K. Jahromi, Changhuei Yang, , | Summary: Diffusing wave spectroscopy (DWS) is a well-known set of methods to measure the temporal dynamics of dynamic samples. In DWS, dynamic samples scatter the incident coherent light, and the information of the temporal dynamics is encoded in […]

Starting Dynamics of a Fully Electronically Controlled Linear Mamyshev Oscillator

Posted by klaurent Cornell

Kavli Affiliate: Frank Wise | First 5 Authors: Yi-Hao Chen, Pavel Sidorenko, Frank Wise, , | Summary: We start an environmentally-stable linear Mamyshev oscillator with electronically-controlled modulated pump and a moving filter. It delivers a 21-nJ pulse that becomes 65 fs in duration after a compressor. Reliable starting into stable mode-locking is found achievable with […]
