摘要
聚合炔（ＰＤＡｓ）材料有较大的非线性光学效应，在全光设备中有较大的潜在应用前景。本文分别研究了尿烷取代聚二乙炔的增强吸收和粗糙界面的光限幅特性，并分析了其限幅机理，发现粗糙界面光限幅比增强吸收光限幅有更好的光限幅特征。
Polydiacetylenes have great potential applications in alloptical devices due to their large third-order nonlinear optical effect.In the paper,optical limiting effects of enhanced absorption and coarse interface enhanced scattering of polydiacetylene substituted by urethane(poly 4BCMU)were investigated and the mechanism of optical limiting was analyzed.It was discovered that the optical limiting effect of coarse interface enbanced scattering of poly-4BCMU was better than that of the enhanced absorption scattering.
