The authors demonstrate mode-locked two-wavelength synchronized operation of a single, cw pumped Ti:Sapphire laser. There is no active feedback or external cavity. The measured cross correlation is 105 fs. Wavelengths as much as 57 nm apart can be simultaneously cross-mode-locked. They then investigate the nonlinear interactions between the pulses. They show the nonlinear interaction caused by self focusing scan correct for a difference in cavity lengths of up to {+-}3{micro}m corresponding to 20% of the pulse width on each round trip. Further, they 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.
