The optical nonlinearity of the tetracarbonyl(2,2ʹ-bipyridyl)chromium(0) in chloroform solution was investigated utilizing zscan technique. The basic parameters were estimated from the fitting of the experimental data, including the nonlinear coefficient (β), the nonlinear refractive index (n2), the cross section of absorption ground-state (σg), the cross section of absorption excited-state (σex) and thermo-optic coefficient. The resulting values σex>> σg have confirmed that the studied compound has the property of reverse saturable absorption (RSA) mechanism. Our results show that the value of β is negative; it decreases with increasing the input power irradiance (I0) and the variation of nonlinear refractive index (n2) due to thermal effect. The tetracarbonyl (2,2’-bipyridyl)chromium(0) might have a potential application in the optical limiting field..
