Paper Abstract

In this paper, optical limiting effect based on stimulated Brillouin scattering (SBS) in a nonlinear medium has been demonstrated. First, nonlinear propagation has been numerically analyzed and computationally treated in the transient SBS progress. Optical limiting, stabilization and output pulses have been shown theoretically when high-power laser pulses enter a SBS medium. Experimental investigation of optical limiting performances predicted by theory has been conducted within a nonlinear medium CCl4. The input optical signa is Nd:YAG nanosecond laser pulse with width 2ns. The limiting characteristics depending on varied physical parameters such as focus, cell length of SBS medium CCl4 and separation between cell and lens have been investigated. The good pulse shape of envelope of the transmitted pulse train and a superior constant output energy have been obtained when the SBS occurs. The relative fluctuation for transmitted signal is about ± 7% while relative fluctuation for laser pulse is ± 13%.
