  2. In succession, the theory of chirped - pulse amplifier system is given in detail, firstly, studying from designing experimental light road and optical components to theoretical analysis, we par ' tly finished the system by ourselves. about ultr a - shoft pulse with a pulse - width of 9. 8f s and output power of 650mw and band - width of about l 20nm is output from oscillator source, secondiy, the stretching capacity of single grating four - pass stretcher is measured using abcd matrix combining collins function, and the effect of relativ e parameters to the streching ratio is also simulated. thirdly, a new type of disjunctional frequency moduiating function is provided according to the gain - narrowing and gain - saturation which are appeared in the co urse of amplification, under modulating the two effects are both controlled on some e xtent, fourthiy, the effect of ase that is often ignored by people is analyzed and the resolving methods are also given

    從光路、光學元件的自行設計到理論分析計算，初步建立了一臺實驗系統；採用abcd矩陣法結合collins公式計算了四通式單光柵展寬器的展寬量，並模擬了相關參數對展寬比的影響，對實驗具有指導意義；評價了再生放大器和多通放大器的優缺點，對放大過程中通常忽略的放大自發輻射現象（ ase ）進行了分析，並提出了相應的解決方法；針對放大過程中出現的增益窄化和增益飽和現象，對輸入種子脈沖提出了一種新的分段頻率調制函數，實現了對增益窄化效應和增益飽和效應的共同抑制；提出了系統的材料（包括放大介質和光路中的普通介質）正是融合高階色散的來源。
