摘要: Abstract Results of DC field poling and second harmonic generation experiments on a thin film polymethyl methacrylate (PMMA) polymer doped with the dye molecule (3-(1,1-dicyanothenyl)-1-phenyl-4, 5-dihydro-1H-pryazole) (DCNP) are reported. The temporal variation SHG signal upon application static (DC) electric at temperature close to glass transition Tg PMMA establishes rapidly, within 66 s. A large value order NLO susceptibility d pp ( - 2 ω ; , ) 52 ± 8 pm/V 1064.2 nm fundamental wavelength was observed. Its possible origin is proposed discussed.
