Spectroscopic Properties of Cr,Yb:YAG Crystals
Source abstract
Abstract
Cr,Yb:YAG laser crystals codoped with 10 at.% Yb and different concentration Cr were grown by the Czochralski method. The absorption spectra, fluorescence spectra, and fluorescence lifetimes of Cr,Yb:YAG crystals were investigated at room temperature. With the increase of Cr concentration in Cr,Yb:YAG crystals, the absorption coefficient at 1.03μm increases, and the fluorescence intensity and lifetime decrease, the energy transfer efficiency from Yb3+ to Cr4+ increases and the quantum efficiency in Cr,Yb:YAG crystals decreases. The optimum Cr concentration for Cr,Yb:YAG crystals was estimated.
