%X In the paper, we have obtained nonlinear absorption coefficient and nonlinear refractive index as a function using transmission spectra for ZnSe thin film. And observed increasing absorption optical bistablity using nanosecond pulsed laser in ZnSe thin film at 77K. The results indicate that the major excitonic nonlinear mechanism is due to Coulomb screening of the excitonic state.
