Abstract

Femtosecond optical pulses with a duration of 200 fs were generated using a GaInN bisectional laser diode passively mode-locked in a dispersion-compensated external cavity with spectral filtering performed outside the cavity. The fact that the femtosecond pulses were obtained with a negative intracavity group-velocity dispersion and a saturable absorber recovery time of about 15 ps indicates that the mechanism involved was soliton mode-locking. The spectro-temporal investigation of the output pulses directly emitted after the mode-locked laser diode revealed that the spectral broadening was due to self-phase modulation in the gain section.
