Analytical model for the intensity dependence of 1500 nm to 980 nm upconversion in Er${}^{3+}$: a new tool for material characterization

Jeppe Christiansen, Harish Lakhotiya, Emil Eriksen +3

We propose a simplified rate-equation model for the 1500 nm to 980 nm upconversion in Er${}^{3+}$. The simplifications, based on typical experimental conditions as well as on conclus…
