Abstract

The amplification of 20-fs-duration pulses in an amplifier with spatial dispersion in the gain medium (dye) is theoretically analyzed. Pulse self-shaping was observed during amplification, and further shaping was achieved by spatially modulating the pump. This spatial modulation of the pump permits the elimination of pulse broadening in the amplifier, even in the saturation regime. The possibility of using a compound medium with an ultrabroadband gain profile is also discussed.
