摘要：

The pulse formation in a femtosecond Ti:sapphire laser was numerically simulated, and the discrete distribution of self-phase modulation and dispersion inside a cavity was found to yield a significantly different pulse formation from ideal solitons. It was verified that, due to the discreteness, the thickness of a Ti:sapphire crystal, as well as the dispersion, was the main limiting factor of pulse shortening in a similar to10-fs Ti:sapphire laser. The unique high-order dispersion characteristics of quartz prisms for dispersion compensation was found to be effective in overcoming the pulse-shortening limit imposed by the discreteness.
