Paper Abstract

Mechanisms of refractive index changes in intensively pumped Yb-doped crystals (Yb:YAG, Yb:KYW, Yb:KGW, and Yb:YVO4) were studied using both a polarization interferometer and the transient grating method at the testing wavelength of 633 nm. The electronic component strongly predominated over thermal index changes in the experimental conditions. The polarizability difference of the excited and unexcited Yb3+ ions (of the ground state and the excited metastable level 2F7/2) was determined.
