Timing jitter and pulse energy fluctuations in a passively mode-locked two-section quantum-well laser coupled to an external cavity

Stability of pulse energy and timing in a passively mode-locked two-section quantum-well laser is measured. Spectral analysis of the 546-MHz pulse train reveals rms timing jitter of 5.5 ps above 50 Hz and rms pulse energy fluctuations of <0.52% above 200 Hz.
