Comparison of spectroscopic parameters of 15 at% Yb: YAlO3 and 15 at% Yb: Y3Al5O12

Yb: YAlO3 (YAP) (15 at %) and Yb: Y3Al5O12 (YAG)(15 at %) have been grown using the Czochralski method. Their absorption and fluorescence spectra were measured at room temperature and important spectroscopic parameters were calculated. Through the comparison of spectroscopic parameters of Yb:YAP and Yb: YAG, all results indicate that 15 at % Yb:YAP crystal is a potential candidate used for compact, efficient thin chip lasers when the laser output wavelength is 1012 or 103 8 nm.
