Potassium lithium tantalate niobate K3Li2(TaxNb1-x)(5)O-15 crystal was grow
n by top-seeded solution growth method. Crack-free crystal in a size of 4 x
5 x 15 mm(3) was obtained. The as-grown crystal was demonstrated to be in
a multidomain state by chemical etching. Single domain crystal was obtained
by applying a DC electric field at an elevated temperature. The crystal wa
s used to double the frequency of 1.06 mu m of the Nd:YAG laser at room tem
perature by non-critical phase matching. (C) 1999 Elsevier Science B.V. All
