博士 === 國立交通大學 === 光電(科學)研究所 === 83 === In this dissertation, we established a general but simple analytic spatio-temporal approach to study both standing and traveling wave Kerr lens mode-locked (KLM) laser resonators. This theoretical approach is based on the abberationless theory of self-focusing and space-time analogy. In our model, we can simultaneously consider various spatial and temporal effects including self-focusing, free space propagation, group velocity dispersion, dispersion compensation, bandwidth limiting, near resonance phase shift, nonlinear absorption, and self-phase modulation. We had also successfully applied these analytic results to construct a completely self-starting femtosecond KLM Ti:sapphire laser by soft-aperturing method. The starting time is less than 0.5 ms, which maybe the fastest starting time that has ever been reported to our knowledge.
