采用动态全息技术研究了富勒烯掺杂聚酰亚胺6B的激光诱导折射率。计算了化合物的非线性折射率eta(2)和非线性光磁化率x(3)。讨论了光谱效应、热效应和光折变效应在纳米和皮秒脉冲激光照射下全息光栅记录中的作用。所研究的材料的位置在其他非线性光学系统中已被发现。(C) 2003 Elsevier B.V.版权所有
Laser-induced refractive index in fullerene-doped polyimide 6B has been investigated by the dynamic holographic technique. Nonlinear refractive index eta(2) and nonlinear optical susceptibility x(3) of the compounds have been calculated. The role of spectral, thermal, and photorefractive effects in the holograpic grating recording under nano- and picosecond pulsed laser irradiation has been discussed. The place of the materials studied has been found among other nonlinear optical systems. (C) 2003 Elsevier B.V. All rights reserved.
