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.
