Abstract
The carrier dynamics in an InGaAsP quantum-well laser amplifier excite d by an ultrashort optical pulse is investigated experimentally as wel l as theoretically. For operation in the absorption region, a transiti on from pump induced cooling to pump induced heating of the carriers i s observed for increasing pump pulse energy and is attributed to the g eneration of hot carriers through two-photon absorption. The results f urther support the interpretation of the carrier dynamics in the pertu rbative regime.
