英文摘要	A new, to our knowledge, neodymium-doped lanthanum calcium borate crystal (nd3+:la2cab10o19, nd:lcb) has been grown by the flux method. the spectroscopic parameters for nd:lcb crystal have also been calculated based on judd-ofelt theory. the intensity parameters omega(t) are omega(2) = 4.96 x 10(-20) cm(2), omega(4) = 3.94 x 10(-20) cm(2), and omega(6) = 3.71 x 10(-20) cm(2). the radiative lifetime tau(r) is 349 mu s. the absorption band at 800 ran has a fwhm of 12 nm. the absorption cross section is sigma(a) = 2.40 x 10(-20) cm(2), and the emission cross sections at 1070 nm are sigma(x) = 3.02 x 10(-19) cm(2), sigma(y) = 2.33 x 10(-19) cm(2), and sigma(z) = 2.68 x 10(- 19) cm(2). the measured fluorescence lifetime (tf) is 64 mu s, and the quantum efficiency eta is 18.3%. in comparison with other nd-doped laser crystals, the calculated parameters show that nd:lcb crystal satisfies the fundamental spectral condition for laser emission.
