Abstract

Cw laser action of Ti:Al2O3 under argon-ion laser pumping is presented. We analyze the free-running characteristics and the effective emission cross section of the laser. The temperature dependence of the 2E lifetime was measured from 4 to 650 K and is explained in a single-phonon model. The quantum efficiency of Ti:Al2O3 at room temperature is 80%.
