摘要：
A photorefractive effect at the wavelength of 1064 nm 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 65 cm(-1), respectively, at 80 V/mu m for a nanocomposite containing 0.25 wt% crude nanotube material. The refractive index modulation measured at E-0 = 50 V/mu m is close to Delta n = 0.004. (C) 2005 Elsevier Ltd. All rights reserved.
