摘要：
Melamine formaldehyde resin (MF) films with good optical quality could be fabricated easily by controlling the initial molecular weight. It was used as a matrix of nonlinear molecules. The optical properties of nonlinear molecules guest-host and covalent-bonded type of poled polymer systems were investigated. The optical propagation losses are around ldB/cm at 1072nm for two kinds of films studied The in situ corona poling second harmonic generation (SHG) method and UV-visible absorption measurement were used. The experiment results showed that the materials we fabricated have improved second-order susceptibilities and higher thermal stability.
