The pump pulse of a hybridly mode-locked laser provides additional parameters for system optimization. We use a semiclassical model to explore numerically the role of the pump pulse in the ultrashort pulse production of a hybridly mode-locked dye laser. Pump pulses of lengths less than ~1 psec are found to correspond to Dirac delta functions and deliver the shortest output pulses. We conclude that existing dye-laser systems would yield a twofold to threefold shortening in output pulse widths and a threefold to fivefold increase in peak power if pump pulses of 1 psec were used. We note that a 1-psec pump pulse is attainable using fiber-compression techniques.
