摘要：
On the basis of de Vries' solution, second-harmonic generation (SHG) spectra in ferroelectric liquid crystal with a twist defect were calculated. It is shown that the SH intensity enhanced by the defect increases with the thickness below the crossover length (L-co) and saturation of SH intensity occurs beyond Lco. (c) 2006 Elsevier B.V.
