Growth and Characterization of Crystal Nd0.06Y0.94Sr6Sc(BO3)6

The crystal of Nd0.06Y0.94Sr6Sc(BO3)6 with the dimensions up to 35 mm ( 28 mm ( 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 (A), and the absorption coefficient is 2.17cm-1 with a FWHM of 41 (A), 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 Ω (() (( = 2, 4 and 6) of the Nd3+ ion in the crystal were calculated as follows: Ω2 = 1.194 ( 10-20, Ω4 = 4.186 ( 10-20 and Ω6 = 3.351 ( 10-20 cm2, 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.
