Paper Abstract

This paper reports optimization of the parameters of a colliding pulse mode-locked (CPM) femtosecond pulse laser including compensation of the dispersion. Our analysis based on the CPM laser dynamics. Seven parameters in the suitable value range have been selected. By using statistics law, we optimized eighteen optimal conditions of the laser operation from thousands conditions. Each laser operation corresponds to certain compensation of proper chirp and group-velocity dispersion, so that the optimum conditions are obtainted for a femtosecond laser with self-phase modulation, group-velocity dispersion, saturated gain and unsaturated gain, saturated absorption and unsaturated absorption. The optimization results also show that the pulse duration can be directly reduced to -10fs by properly increasing the unsaturated gain and the dynamics self-equilibrating capability of dispersion compensation.
