摘　　要：实验研究了单池系统的结构参数对受激布里渊散射（ＳＢＳ）脉冲波形的影响，通过改变透镜焦距、透镜与池的距离可以很容易地在１．５～８ ｎｓ之间调节ＳＢＳ脉冲宽度。利用含有受激布里渊散射噪声的理论模型对ＳＢＳ脉冲波形进行了数值模拟。The influence of configuration parameters in a one cell system on the pulse waveform of stimulated Brillouin scattering was investigated experimentally. The Stokes pulsewidth was easily changed from 1.5 to 8 ns by varying the lens focus and the distance between the lens and the SBS cell. The SBS pulse waveform was numerically simulated by the theory model of stimulated Brillouin scattering initiated by thermally excited acoustic waves. The theoretical calculation was coincident with experiment results well.
