K3V5O14-a New IR Nonlinear Optical Material

Keywords： infrared , nonlinear optical material , K3V5O14

作为红外非线性光学材料,氧化物和磷铜铁矿半导体材料的透过光谱可到中远红外谱区,但它们的晶体损伤阈值很低.本文提出并合成一种新的红外非线性光学材料五钒酸钾-K3V5O14,它的空间群是P31m,透过光谱范围可达到10μm,而且其粉末倍频效应大于KDP晶体的20倍.

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.
