This paper reports the spectroscopic properties of Yb3+:Li3Ba2Y3(WO4)8 crystal. The polarized spectral properties of Yb3+:Li3Ba2Y3(WO4)8 crystal were investigated. The laser performance parameters ¦Âmin, Isat and Imin of Yb3+:Li3Ba2Y3(WO4)8 crystals have been also established. Yb3+:Li3Ba2Y3(WO4)8 crystal has a broad FWHM of the gain cross-section and larger absorption and emission cross-sections. These results may regard the Yb3+:Li3Ba2Y3(WO4)8 crystal as a tunable laser material.
