Growth and characterization of

Abstract
A new laser crystal Nd0.05La0.95Sc3(BO3)4 up to 50mm×38mm×7 mm was grown by top-seeded solution growth method from a Li6B4O9 flux. The grown crystal was characterized by X-ray powder diffraction. Its crystal structure is monoclinic with space group Cc and the unit cell dimensions: a=12.066(5), b=9.864(2), c=7.740(3) Å,β= 105.48(5)°, V=887.8(6)Å 3 , Z=4, Dc=3.81g/cm 3 , which belongs to low-temperature phase. The optical absorption of the crystal shows that NLSB has a strong absorption band at 807.7 nm, which is suitable for laser-diode pumping.
