摘要：

DR1 (4-[N-ethyl-N-(2-hydroxyethyl)]amino-4'-nitro-azobenzene) doped silica films were prepared by a sol-gel method, from a solution of tetraethyl orthosilicate and DR1, The films were optically poled and heat-treated to build a polarized structure for second-order optical nonlinearity. Two seed beams at 1064 and 532 ma wavelengths from a Q-switched Nd:YAG laser were coaxially applied to the films. Second-harmonic generation was observed from the films after the optical-poling. We found that the rigid silica matrix prevented the relaxation of polarized structure.
