15 February 2012 Refractive indices and thermo-optic coefficients of Erbium-doped Yttria
Author Affiliations +
The refractive indices and thermo-optic coefficients for varying concentrations of Er3+ doped polycrystalline yttria were measured at a variety of wavelengths and temperatures. A Lorenz oscillator model was employed to model the room temperature indices and thermo-optic coefficients were calculated based on temperature dependent index measurements from .45 to 1.064 microns. Some consequences relating to thermal lensing are discussed.
