研究了芳香聚酰亚胺和碳单壁纳米管的复合材料在1064nm波长处的光折变效应。对于含0.25wt%粗纳米管材料的纳米复合材料，在80V/μm下，双光束增益耦合系数和净增益系数分别为90和65cm−1。在E0=50V/μm处测得的折射率调制接近Δn=0.004。
A photorefractive effect at the wavelength of 1064nm is demonstrated for a composite consisting of an aromatic polyimide and carbon single wall nanotubes. The two-beam gain coupling coefficient and the net gain coefficient are equal to 90 and 65cm−1, respectively, at 80V/μm for a nanocomposite containing 0.25wt% crude nanotube material. The refractive index modulation measured at E0=50V/μm is close to Δn=0.004.
