Abstract
This work studies the two-photon luminescence spectra of a Yb3+doped YAG crystal grown using the Czochralski method. To study the spectral performance of a 50 at.% Yb:YAG crystal, intense green light (centered at about 544nm) was generated by the crystal upon excitation using a 973nm InGaAs LD pump source. The luminescence spectra were obtained for various Yb concentrations and the emission intensity were plotted versus Yb3+concentration. The green emission light attributed to Yb3+two-photon transition.
