The growth of Nd3+: GdxY1-xAl3(BO3)(4) crystals

Large crystals of Nd3+ : Gd0.2Y0.75Al3(BO3)(4) with a size of up to 32mm ha ve been grown from a 90 wt% K2Mo3O10 : 10 wt% B2O3 flux. The liquids temper ature curve for this growth system was determined by repeated seeding. From the grown crystal boule, a high-quality laser bulk crystal with dimensions of 4 mm x 5 mm x 6 mm was cut out, and the absorption spectrum was measure d. A laser output at 0.532 mu m was realized when this crystal was pumped b y a laser diode. (C) 1999 Elsevier Science B.V. All rights reserved.
