| 摘 要： | 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.

| 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_3V_5O_(14) crystal belongs to the space group P31m. K_3V_5O_(14) 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 K_3V_5O_(14). The results show that K_3V_5O_(14) is a new promising nonlinear optical material in the infrared region. |
