Abstract

Decay curves of 1.5 μm (4I13/2) and 980 nm (4I11/2) emissions from Er3+ ions in Ga2S3-GeS2-La2S3 glasses were measured by the excitation of 1.5 μm laser diode pump. The decay curves were simulated using rate equations for a model consisting of four levels (4I15/2, 4I13/2, 4I11/2, and 4I9/2) of Er3+. A pair of unknown parameters, i.e., an excited state absorption coefficients for 4I13/24I9/2, σesa, and a cooperative upconversion coefficient for (4I13/2, 4I15/2)→(4I9/2, 4I15/2), C, were included in the rate equations. They were estimated by fitting the simulated curves to the measured ones. The obtained values were 3×10-21 cm2 and 1 or 3×10-21 cm3/s for the σesa and C, respectively.
