Ultrashort pulse generation by intracavity spectral shaping andphase compensation of external-cavity modelocked semiconductor lasers

摘要

Intracavity spectral shaping and external chirp compensationntechniques were employed to generate nearly transform-limited opticalnpulses with a temporal duration of 250 fs from an external-cavitynmodelocked semiconductor laser. It was also demonstrated thatnintracavity spectral shaping techniques can be used for artificiallyntailoring the chirp of the output pulses
