The third-order optical nonlinearity of the composite film of coordination complex [CoLPPh3Cl] (L= N-(2-pyridyl)-N'-(salicylidene)hydrazine) and PMMA has been investigated by using Differential Optical Kerr Gate (DOKG) and Z-scan measurements. Large value of the third-order nonlinear optical susceptibility (chi((3))) of the order of 10(-10) esu was measured and its nonlinear response time was found to be faster than or comparable to the laser pulse width (90 fs) used. The single beam Z-scan technique was used to investigate the nonlinear absorption property of the composite near 800 nm. The sample exhibit saturable absorption. The nonlinear absorption coefficient of sample is found to be -32 cm/GW. (C) 2010 Elsevier B.V. All rights reserved
