Abstract

The amplification of ultrashort optical pulses in semiconductor laser amplifiers has been the subject of considerable research interest in recent years, because of the potential applications in high-speed communications and logic systems. Flared single-pass amplifiers have achieved the highest coherent CW output power [l] and can give very good results also for pulsed operation [2]. In this paper we present for the first time a systematic investigation on the contribution of the various physical effects to the pulse amplification and to the temporal, spatial and spectral behavior.
