在本研究中，我們成功地討論多重延遲光回饋系統對雷射輸出動態的影響。在傳統單一光回饋系統下，當光回饋強度較小時，在短腔長的情形可以呈現穩定動態和震盪週期動態， 隨著腔長增長和光回饋強度增強，會開始出現準週期震盪動態和混沌動態。然而，在多延遲光回饋系統，我們先藉由粒子擴散產生多重延遲光回饋系統，進而探討隨著延遲數目的增加，使得光回饋強度均勻分布在連續的高斯分布形貌下， 使得雷射輸出動態從原本的混沌動態轉變為穩定動態。接著，改變不同的參數亦會對雷射輸出動態造成影響，因此，我們發現要得到較多的穩定動態必須：
1. 粒子間的間距要小於22.5 mm ( 0.15 ns)。
2. 粒子起始位置要越靠近雷射越好。
3. 粒子間的相位不同相可以使回饋強度較強的區域可以得到穩定動態。
4. 雷射到粒子間的相位變化要在0 附近。
藉由以上這四點的參數的選擇，我們可以在多重延遲光回饋系統下得到不同於單一光回饋系統的結果， 而使雷射的輸出動態趨於穩定。而粒子分布的形貌對於雷射動態的影響甚小，只要是在多重延遲光回饋系統下，延遲數目達到一定數量後都可以使雷射輸出穩定動態。
