Demonstration of site-selective angular-resolved absorption spectroscopy of the ${}^4{I}_{15/2}\to$${}^4{I}_{13/2}$ erbium transition in the monoclinic crystal Y${}_2$SiO${}_5$

Yannick Petit, Benoît Boulanger, Jérôme Debray +1

We study the angular dependence in polarized light of the optical absorption for the Er${}^{3+}$ transition ${}^4{I}_{15/2}\to$${}^4{I}_{13/2}$ in Y${}_2$SiO${}_5$, revealing thus…
