碩士 === 國立彰化師範大學 === 光電科技研究所 === 93 === Solid-state lasers and solid-state saturable absorbers are not new in scientific knowledge. But, they included a lot of important laser principles and theorems. Up to now, these principles and theorems are of great use, such as semiconductor lasers and high brightenss LED. For example, ruby laser, it is the first laser in our world. It proved that excited emission theorem of Population inversion of Albert Einstein. Today, in new light source and signal communication source, solid-state laser have be replaced with LED and semiconductor laser. But, in cosmetic surgery or researches of laser theorem, they are still very important. Numerical analysis is an index in various researches. It is in concert with physics theorems and logical operation in astronomy, meteorology, propagation of organism, nuclear fission, nuclear fusion, semiconductor laser and high brightness LED. In fact, we can not control perfectly every parameter that we know or we don’t know. So we must combine and compare the results of numerical analysis and experiment. In others words, results of our numerical analysis can be an index for our experiments. And then, when we got the results of our experiments, we can take these to compare and reform numerical analysis parameters. We do it step and step, again and again, try and error. We would find a lot of information with our research. With speed of center processing unit is more and more fast and capacity of hard disk is more and more big, research of numerical analysis developed quickly. Every kind of mathematical software occured one by one. For example, Matlab, which combined program language and calculation tool boxes. The thesis focus on that simulation of Dy:CaF2 and Cr:YSO Q-switched ruby laser and Nd:YAG-Cr:YAG dual Q-switched ruby by Matlab rate equations program.
