| The linear and nonlinear optical response of colloidal PbSe nanocrystals was investigated. Optical nonlinearity and its recovery dynamics in this system was measured and compared with other available experimental data. The saturation irradiance value for the bleaching effect and absorption cross-section were determined. |
