Polarization and Crystal-Orientation Dependency of Thermal Effects in Cryogenically Cooled Yb:CaF 2 (poster)
Abstract
We study beam polarization and crystallographic-orientation dependency of thermal effects in Yb:CaF2 crystals at LN2 temperature. AtypicalSignificant anisotropy for a cubic crystal is demonstrated resulting in polarization-dependent thermal-astigmatism or asymmetric depolarization pattern.
