Abstract :
Numerical simulations using the transmission-line laser model show that the instantaneous frequency of a 10 ps mode-locked pulse undergoes a rapid red-shift of 60 GHz during the first half of the pulse followed by a slow recovery of 10 GHz. Self-phase modulation is thought to cause this shift.
