摘要
Tm 3 + : GdAl 3 ( BO 3 ) 4 crystals were grown successfully from K2Mo3O10-B2O3 solvent by using the top seeded solution growth method. The absorption spectra for both σ and π polarizations were presented. The Judd-Ofelt (J-O) intensity parameters were found to be Ω2=4.54×10−20cm2,Ω4=2.25×10−20cm2, and Ω6=3.39×10−20cm2. The spectroscopic parameters of this crystal such as the oscillator strengths, radiative transition probabilities, radiative lifetime as well as the branching ratios were calculated. Unpolarized and polarized emission spectra were obtained under the excitations of 468 and 797 nm, respectively. This crystal may be preferable for GaAlAs laser pumping.
