| 摘 要： | 非线性效应使激光光强限制在１０９ Ｗ／ｃｍ２ 量级。在过去十年间，各国科学工作者利用啁啾脉冲放大技术（ＣＰＡ 技术） 将激光光强提高到１０２０ Ｗ／ｃｍ ２ 量级。文章就ＣＰＡ 技术中的短脉冲放大，展宽／ 压缩比的调节及大光谱脉冲的放大等问题作了具体讨论。最后，还以惯性约束核聚变（ＩＣＦ） 点火器为例，讨论了超高光强激光的应用。

| Abstract: | Nonlinear effect makes the laser intensity stay at 10 9 W/cm 2.In the past ten years,the intensity has been enhanced to as high as 10 20 W/cm 2 by using the chirped pulse amplification(CPA).In the article we discuss generation of the ultrashort pulse,the accommodatiom of spreading/compression ratio and the amplification of the ultrahigh-intensity laser.Finally,taking the ICF fast ignitor as an example,the application of the ultrahigh-intensity laser is presented. |
