The crystal of Nd(0.06)Y(0.94)S(r)6Sc(BO3)(6) with the dimensions up to 35 mm x 28 mm x 13 mm was grown by a top-seeded solution growth method from Li6B4O9 flux. The grown crystal was characterized by X-ray powder diffraction. The optical absorption of the crystal shows that it has a strong absorption band at 8070 Angstrom, and the absorption coefficient is 2.17cm(-1) with a FWHM of 41 Angstrom, which can match with the wavelength of the diode-laser (LD) and is suitable for the LD pumping. Based on the Judd-Ofelt theory, the three parameters of line oscillator strength Omega((lambda)) (lambda = 2, 4 and 6) of the Nd3+ ion in the crystal were calculated as follows: Omega(2) = 1.194 x 10(-20), Omega(4) = 4.186 x 10(-20) and Omega(6) = 3.351 x 10(-20) cm(2), Which are relatively larger. The results indicate that the crystal Nd0.06Y0.94Sr6Sc(BO3)(6) may be a kind of high-efficient laser material for diode-pumped. 展开更多
