Dielectric multilayer mirrors designed as Gires–Tournois interferometers have been used in a colliding pulse mode-locked dye laser to study the influence of intracavity group velocity dispersion on the pulse formation. Simple angle tuning of the interferometric mirrors which is equivalent to a change of the net cavity dispersion resulted in a shift of the laser wavelength between 627 and 614 nm. Within this range stable operation with pulse durations of 130 fs or less and average output powers between 30 and 80 mW was obtained. The shortest pulse of 80 fs duration was found at 626 nm.
