Abstract : The optical properties of Er3+ doped Ca2Al2SiO7 CAS and SrLaGa3O7 SLG are described in this paper. Er3+ solubility is determined for the two laser hosts. Cross-relaxation processes and multiphonon desexcitation are observed and the relative rates are calculated with the frame of the Judd-Ofelt analysis. Er:SLG presents some longer lifetimes and smaller multiphonon non radiative contribution than the Er:CAS. Both laser hosts present a broad and intensive emission around 1.5 µm. In this paper are also discussed the mechanisms that can reduce the laser oscillation efficiency.
