Effects of Cavity Dispersion on Femtosecond Mode-Locked Dye Lasers
- 128 Downloads
Significant progress has recently been made in the generation of femtosecond dye laser pulses, in particular by means of the colliding pulse technique . Some observed features of the mode-locked (ML) laser still remain largely unexplained, however. In a few cases, for instance, a strong negative frequency chirp has been experimentally observed  and attributed to a phenomenon of self-phase-modulation (SPM) arising from the saturation of the saturable absorber . In other cases, the choice of the cavity mirrors  and their layout in the laser cavity  have been shown to influence the pulse duration.
