Paper Abstract

Characterization of thermal conductivity with temperature dependence is much important for designing of the high power lasers. A simple model of thermal conductivity for various optical materials, such as Y3Al5O12, YVO4, GdVO4, stoichiometric and congruent LiTaO3, and synthetic quartz, has been established: one parameter for specific heat and two parameters for thermal diffusivity. Authors also discussed the dependence of laser active ion doping concentration such as Yb3+ or Nd3+. This thermal conductivity model was verified from room temperature to 200°C in the various optical materials.
