Second-harmonic generation(SHG) of stilbazium salt Langmuir-Blodgett monolayer film in the different surface pressure was measured. We got the incremental SHG signal at the low surface pressure. After the transparent spectra of stilbazium salt were measured
we got the following results. The stilbazium salt on LB film was in the form of solid state. The absorption peak 351 nm of the aggregation of solid state at the low surface pressure led to that the fourth order nonlinear optical susceptibility
