Abstract
Potassium titanyl arsenate (KTiOAsO4, KTA) crystals have been grown wi th flux method. The infrared absorbing edge of KTA crystal is about 5. 3 mum. The electric and other properties of KTA were measured. Accordi ng to the x-ray orientating, KTA crystal samples were prepared to carr y on second harmonic generation (SHG) and sum frequency generation (SF G) experiments. The SHG efficiency of KTA for Nd:YAG is 1.7 times larg er than that of KTA. At 20-degrees-C, the shortest SHG wavelength is 0 .5174 mum, and the shortest SFG wavelength is 0.4994 mum.
