Resum: Stimulated-emission cross-section spectra are determined for the ~1.5 ?m and 3 ?m transitions of Er3+ ions in YSGG crystal. For the 4I11/2?4I13/2 channel, the maximum stimulated-emission cross-section ?SE is 0.43×10-20 cm2 at 2797.1 nm. For the 4I13/2?4I15/2 channel, ?SE=1.20×10-20 cm2 at 1532.8 nm. Due to the reabsorption loss, laser operation is expected at ~1644 nm. Radiative lifetimes of all excited states of the Er3+ ion from 4I13/2 to 2H9/2 and probabilities of radiative transitions from these states are determined using the Judd-Ofelt theory. Radiative lifetimes of the 4I13/2 and 4I11/2 excited states for Er3+ ions in YSGG are 7.73 ms and 9.75 ms, respectively. Non-radiative decay is analyzed for lower excited-states of Er3+ ions in YSGG. © 2015 Elsevier B.V. All rights reserved.
