Cross-locking dynamics in a two-color mode-locked Ti:sapphire laser.
We investigate the nonlinear interactions between pulses of two different wavelengths within a single cross-mode-locked femtosecond Ti:sapphire laser. We show that the nonlinear interaction caused by self-focusing can correct for a difference in cavity lengths of as much as +/-3 microm, corresponding to 20% of the pulse width on each round trip. Further, we show that the concept of mean group delay can be extended to a pair of pulses with disparate spectra and spatial distribution in a nonlinear regenerative system.
