The main part and key technique of the cpa system is study : the generation of the femtosecond laser pulse is study, the modulation and maintenance of the ti : s laser is learned ; the types of the measurement for ultrashort laser pulse is generalized and the interferometric autocorrelation is expatiated ; the varieties of the stretchers is sum up and aberration - free stretcher is calculated and optimized to improve the stretching ratio ; the pulse selection is analyzed and a single pulse can be selected successful from the pulse train at a repetition rate of 82mhz ; the kinds of the amplifier in cpa system is gathered up, the eight - pass pre - amplifier and a good many effects in it is investigated. finally, the second, third and fourth - order dispersions in cpa system is analyzed systemicly, and the according means for dispersion compensation is worked out
對cpa系統的主要環節及關鍵技術進行了研究：掌握了鈦寶石激光器的調節和維護技術，較深入地研究了飛秒激光脈沖產生的機理，其中對群速色散、自相位調制、自鎖模等問題進行了詳盡的分析；總結了超短激光脈沖的測量技術，重點研究了干涉自相關測量法；在總結展寬器類型的基礎上，對無象差展寬器進行了理論計算、優化設計，提高了展寬倍數；深入論述了脈沖列的選單問題，熟練掌握了脈沖選單技術。 -
Finally we separate the aberration into space invariant and variant component, which are eliminated by first and second - order compensation procedure respectively. then a method to integrate motion compensation in range - doppler ( rd ) imaging algorithm is presented
