摘要：

TmAl3(BO3)(4) crystallizes in the trigonal system R32 (No. 155) with a = b = 9.2741(13) angstrom, c = 7.218(3) angstrom, alpha = beta = 90 degrees, gamma = 120 degrees, V = 537.7(2) angstrom(3), D-c = 4.494 g cm(-3), and Z = 3. The absorption spectrum of this crystal was recorded at room temperature. The Judd-Ofelt (J-O) theory was applied to the absorption intensities of TmAl3(BO3)(4) to obtain the three J-O parameters: Omega(2) = 2.40 x 10(-20) cm(2), Omega(4) = 0.48 x 10(-20) cm(2), and Omega(6) = 1.09 x 10(-20) cm(2). The radiative probabilities, radiative lifetimes, and branching ratios of TmAl3(BO3)(4) were calculated. The absorption and emission cross sections, together with the potential laser gain near 1.9 mu m, were investigated. The potential laser gain curves indicate that the tunability range is about 200 nm.
