Pre-print: Polarization-Resolved Extreme Ultraviolet Second Harmonic Generation from LiNbO3
Apr 6 2021

We are happy to see Can’s first first-author manuscript submitted on polarization-resolved second harmonic spectroscopy enabling element-resolved angular anisotropy investigations. In LiNbO3 we directly resolve the Li ion displacement and its correlated action on the Nb-O bonds. This study constitutes the first observation of polarization-resolved SHG in the extreme ultraviolet (XUV) and we show that dipole-based SHG models used regularly in the optical regime allow predicting the SHG polarization in the in the XUV regime.
This work as performed at the SACLA free-electron laser at Sping8/RIKEN in primary collaboration with UC San Diego, Argonne National Lab, LBNL and U Tokyo.
