摘要
为了寻找性能良好的受激布里渊散射(SBS)介质,根据SBS对介质的要求,试验了几种全卤代烃新介质。测定或计算了增益系数、声子寿命和吸收系数等参数。四氯乙烯(C2Cl4)具有良好的SBS特性,其增益系数为9.0cm·GW-1,声子寿命为0.59ns,吸收系数为0.003cm-1。分析和讨论了介质化学结构对SBS特性的影响。
In order to find high-quality stimulated Brillouin sc attering (SBS) mediums,experiments have been performed on several full halogena ted hydrocarbon liquid mediums.SBS parameters,including gain coefficient,phono n lifetime and absorption coefficient,are measured or calculated.The medium tet rachloroethylene (C2Cl4) has a gain coefficient of 9.0cm·GW^(-1),phonon lifetime 0.59ns and absorption coefficient 0.003cm^(-1).The influence of che mical construction on SBS characteristics is also discussed.
