這表明空氣槽總是被充氣至最佳程度，而脈沖被減少到可以忽略的地步（單作用泵系統亦然） ，這對于保護進出口閥和齒輪箱免受沖擊，延長它們的使用壽命起著重要的作用。From three - wave coupling equations, the optimal crystal length, conversion efficiency and parametric light pulse width are computed numerically when clbo is used in picosecond optical parametric amplification. the results present that clbo are suited for optical parametric amplification in short wave band. in order to get higher conversion efficiency, the crystal length should be optimized according to the intensities of pump and signal waves
從三波耦合方程出發，對clbo用於皮秒級光參量放大時，最佳晶體長度、轉換效率和參量光的脈沖寬度進行了理論分析和數值模擬，結果表明clbo晶體適合在短波范圍作光參量放大，為達到高的轉換效率和窄脈寬的信號光輸出，泵浦光和初始入射信號光的強度應根據晶體長度取最優化值。
