Abstract
The advantages of mode locking with spatial dispersion in the gain medium are demonstrated in a passively mode-locked dye laser. The cavity design and the value of dispersion necessary to get benefit from the dispersive scheme are discussed. For a given strength of the basic mode-locking mechanism a dramatic reduction of the pulse duration is obtained as compared with the standard case of no dispersion. Pulses shorter than 100 fs are generated in a simple linear resonator at pump powers far above the threshold. Wavelength tuning is obtained over a range of approximately 10 nm.
