摘要

An experimental investigation of the third-order nonlinear optical properties of new poly(2-(5-[3,4-ditetradecyloxy-5-(1,3,4-oxadiazol-2-yl)thiophen-2-yl]-1,3,4-oxadiazol-2-yl}pyridine}(P)in tetrahydrofur-an (THF) solution and in solid poly( methylmethacrylate) (PMMA) matrix, by Z-scan technique isreported. The Z-scan traces reveal that the composite films exhibit large negative nonlinear refractiveindex of the order 10~(-10)esu. The excited-state absorption cross-section was found to be larger than theground-state absorption indicating that the operating nonlinear process is reverse saturable absorption(RSA). The new polymer P exhibits good optical power limiting properties in the nanosecond regime insolution and as well in solid PMMA matrix.
