| Abstract: | The intracavity pulses in colliding pulse mode-locked (CPM) lasers are very intense (reaching peak power densities = 10¹¹ W/cm²) and "ultrashort" (30 fsec is typical). Consequently, nonlinear and transient processes are essential to the intracavity pulse evolution. In this dissertation, the interactions of a pulse with each of the intracavity elements is modelled. This includes consideration of the gain jet, saturable absorber jet, and group velocity dispersion (GVD). The effects of each of these elements on pulse intensity and phase are computed, and finally, pulse evolution in a typical roundtrip is considered. Generally, the detailed analysis presented here explains many of the details of intracavity pulse shaping that were previously not understood, or were merely conjectural. Moreover, the results presented here are quite consistent with observation. |
