Oxides and chalcopyrites semiconductor materials have infrared laser properties noticed in the infrared region, but their application was restricted due to their disadvantages.K3V5O14 crystal belongs to the space group P31m.K3V5O14 has a wide transparency wavelength range and powder double-frequency studies show that its SHG signal is about 20 times larger than that of KDP.This paper reports a new synthesis method and research work for crystal conditions on the K3V5O14.The results show that K3V5O14 is a new promising nonlinear optical material in the infrared region.
