The effect of line width compression of stimulated Brillouin scattering (SBS) is investigated experimentally. It is found that the line width compression is directly related to the compression of pulse duration. A new method of measuring the line width of SBS through measuring the pulse duration is proposed. The temporal coherence of SBS is also investigated. It is revealed that the temporal coherence of SBS varies with the compression ratio of pulse duration. High pulse duration compression and good temporal coherence cannot be obtained simultaneously.
