碩士 === 國立成功大學 === 物理學系 === 103 === The purpose of this study is to generate pulsed Ince-Gaussian(IG) lasers in end-pumped solid-state lasers and to reach different modes of selection and application of Q-switched pulsed lasers. The active Q-switch we adopting in this study is the acousto-optic (AO) modulator. However, we also adopt the chopper in this study. In the first part of the experiment, both of laser systems can be used to generate pulsed IG laser and observe the relaxation oscillation (RO). The second part of the experiment, we study on Q-switched Ince-Gaussian laser generation with AO modulator. Experimental result shows that, using AO Q-switched laser system, this study successfully generates pulsed IG lasers of several different modes. Besides, by classifying IGMs into even and odd groups, this study gives discussions on the relation between pulsed Ince-Gaussian lasers of different modes.
