Abstract:Cr3+:Al2(WO4)3 Crystal was grown from the Na2WO4 solvent system by using the TSSG method. The absorption spectrum shows that there are two strong absorption wideband peaks and one weak absorption peak belonging to Cr3+ ion in the crystal. The peak values of two strong absorption wideband peaks are at 422 and 595 nm, respectively. The values of two weak absorption peaks are at 684 and 663 nm, respectively. The fluorescence spectrum shows that one emission wideband peak ranging from 650 to 820 nm coexists with one stronger emission peak at 680 nm. The peak value of emission wideband is at 740 nm. The crystal field and Racah parameters were calculated, where Dq/B=2.420 indicates that it has an intermediary crystal field. The result shows that Cr3+:Al2(WO4)3 crystal is promising for tunable laser because it not only has the spectral characteristics required for tunable laser crystal but also has the good physicochemical properties.
