| Summary: | 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.
