【摘要】 介绍聚合物DR/PMMA薄膜材料做成光学法布里-珀罗腔结构,通过观察透射率随外加电场变化,以确定其非线性光学特性参量,在室温和575.0nm时的三阶极化率x^⑶（-ω;ω,0,0）=（5.3-i6.0）×10^{（-11）_θs.u}和二次电光系数R=-（8.5-i9.7）×10^-19m²/V².更多还原

【Abstract】 This paper describes the optical Fabry-Perrot cavity made of polymer DR/ PMMA thin film. Prom the observation of the transmission variation with the applied electric field, we can identify the nonlinear optical parameters. For DR/ PMMA we have obtained the third order nonlinear susceptibility x(3)(-ω;ω, 0, 0) = (5.3-i 6.0) ×10-11e.s.u. and quadratic eleotro-optio coefficient R=-(8.5-i 9.7) ×10-19 m2/V2 at 575 nm and room temperature.更多还原
