The optical limiting properties of the mixed liquid of carbon black suspensions(CBS)and green tea solution were studied by using an 8 ns laser pulse at 532nm.The optical limiting effects of the CBS and mixed liquid have been compared between 5 and 10 Hz repetition frequencies with nanosecond laser pulse.The experimental results indicate that the optical limiting threshold of the sample with the incidence laser at 10 Hz repetition frequency is lower than at 5 Hz repetition frequency.The possible reasons for the influence of the repetition frequency on the samples are discussed.And by observing the optical radiant distributions when the laser pulse passing through different samples,a possible mechanism for the observed effects is suggested.At the same time,the result shows that the optical limiting of CBS is the dominant factor to optical limiting ofthe mixed liquid.
