本論文的研究目的是希望於末端激發型固態雷射中產生脈衝恩司-高斯雷射。本論文共嘗試了兩種Q開關。一、被動式Q開關：在平凹共振腔中加入被動式Q開關(Cr4+:YAG)、二主動式Q開關：在共振腔中加入光遮斷器調控共振腔的Q值。研究結果發現，採用兩種Q開關都能產生脈衝恩司-高斯雷射，但使用被動式Q開關難以產生高階的恩司-高斯脈衝雷射且脈衝雷射輸出性質不穩定。利用主動式Q開關時，則可成功地將多個不同種類的脈衝恩司-高斯雷射激發出來，同時，本論文亦對產生的脈衝恩司-高斯雷射進行分類，找出不同模態脈衝輸出間的關聯。
The purpose of this study is to generate pulsed Ince-Gaussian lasers in end-pumped solid-state lasers. This thesis used two kinds Q-switch in generating of pulsed Ince-Gaussian lasers. One is passive Q-switch, and the other is active Q-switch. The passive Q-switch we adopt in this study is the saturable absorber Cr4+:YAG, and the active Q-switch we adopt in this study is the optical chopper. Experimental results shows that, both Q-switch end-pumped solid-state laser systems can be used to generate pulsed Ince-Gaussian laser. However, the pulsed Ince-Gaussian laser beams generated from a passive Q-switch laser system are not stable. And, it is hard to generated high-order pulsed Ince-Gaussian lasers from a passive Q-switch laser system. On the contrary, using active Q-switch laser system, this study successfully generates pulsed Ince-Gaussian lasers of several different modes. Besides; by classifying IGMs into several groups, this study gives discussions on the relation between pulsed Ince-Gaussian lasers of different modes.
