We report on the temperature dependence of L-band laser emission of fiber-taper-coupled Er[sup 3+]-doped tellurite glass microsphere. The microsphere laser emission threshold increased and the emitted laser wavelength shifted with temperature. The experimental results are explained with a quasi-four-level model, showing that a significant reduction of laser threshold can be achieved at lower temperatures and higher Q values of this microsphere laser. © 2003 American Institute of Physics.
