Abstract

We investigate, based on laser performance, the fractional thermal loadings in a Yb3+/Er3+ codoped phosphate glass laser. The results indicate that fractional thermal loading increases with Er3+ doping concentration nonlinearly. Above an Yb3+ doping level, the increase of Yb3+ cannot promote laser performance but induces a more serious heat effect. We investigate the main factors that simultaneously affect laser and thermal performances. The results show that the ratio of laser output power to heat is sensitive to beam overlap efficiency, the laser extraction efficiency, especially to quantum efficiency of laser material. The optimized doping concentrations of Yb3+ and Er3+ are deduced.
