Abstract
Tm-based laser with emission at 2.3 μm could be used to detect atmosphere pollutants and various molecules. Within this work we investigated if oxide compounds could be efficient for this laser emission as complex energy transfers could occur such as non-radiative relaxation and upconversion. Several oxides hosts are investigated, namely CaGdAlO4 (CALGO), Y2O3, CaYAlO4 and CaYAl3O7 to host Tm3+ for laser effect at 2.3 μm. We focus on the optical characterizations and spectroscopic analysis of these materials, determining intrinsic optical features such as lifetime and broadening of the emission bands.
