Characterization and properties of a new IR nonlinear optical crystal: K3V5O14

Abstract Oxides and chalcopyrites semiconductor materials have infrared laser properties noticed in the infrared region, but their application was restricted due to their disadvantages. K 3 V 5 O 14 crystal belongs to the space group P31m. K 3 V 5 O 14 has a wide transparency wavelength range and powder double-frequency studies show that its SHG signal is about 20 times to that of KDP. This paper reports a new synthesis method and research work for crystal conditions on the K 3 V 5 O 14 . These results we found show that K 3 V 5 O 14 is a new promising nonlinear optical material in the infrared region.
