In this paper , the experimental part is the sum - up of theoretical and experimental studies on a 20tw ti : sappire femtoscecond high - intensity laser system while author worked in the research center of laser fusion of caep , which includes oscillator , regenerative amplifier , multi - pass amplifier , stretcher , compressor and synchronization system 本文實驗研究是指作者在激光聚變中心參與的20tw全鈦寶石飛秒超短脈沖激光裝置的工程建設工作的理論與實驗研究總結,對此系統的振蕩器、再生放大器、多程放大器、展寬器與壓縮器及同步系統進行了較為系統的分析。

This is due to the fact that laser beams with a flat - top profile or other kinds of profiles are desired in various applications , such as in the applications of laser fusion , laser heat treatment and optical data processing etc . nevertheless most of study on the beam shaping is concentrated on the beam shaping of spatially completely coherent beams 光束整形之所以熱門,是因為這些特殊形式的光束可應用于激光光學及生物醫學等領域。例如,平頂光束可應用于激光核聚變、激光熱處理等領域。然而,研究者對部分相干光的光束整形的研究還很少。

Abstract : the far - field spot characteristics of laser converted by random phase plate are analyzed theoretically , including the shape , size , rotational symmetry and diffractive efficiency of the spots , as well as the distribution of subsidiary spot . by comparing the influence of phase element shape ( triangular , square and hexagonal ) on the characteristics , we found that the random phase plate with hexagonal array structure is more suitable for the beam smoothing in laser fusion 文摘:從理論上分析了激光經隨機位相板變換后在遠場的光斑特性(包括光斑的形狀、大小、旋轉對稱性、衍射效率以及旁瓣分布) ,通過比較三種形狀位相元(等邊三角形、正方形和正六邊形)的遠場光斑特性,得知正六邊形位相元結構的隨機位相板更適合于激光聚變中的束勻化。

It has been shown that when the partially coherent beams propagate in the atmosphere , it may be less affected by turbulence than are fully coherent ones . moreover in laser fusion a highly coherent beam is transformed into a partially coherent beam , for reducing the speckle and for getting more smooth focused spot 例如,部分相干光在大氣中傳輸時所受大氣騷動的影響要比完全相干光小得多;并且部分相干光束具有光強比較均勻,對散斑低靈敏等優點而被應用于激光核聚變等領域。

After signing comprehensive nuclear - test - ban treaty ( ctbt ) , laser fusion , as the best . technological way of controlled fusion , got the big countries “ great attention 全面核禁試條約簽訂后,激光核聚變作為受控核聚變的最佳技術途徑,得到各核大國的高度重視。

Laser plasma interaction is a typical nonlinear problem and one of the key issues in laser fusion 激光等離子體相互作用是一個典型的非線性問題,是激光聚變研究的核心問題之一。
