We examined the influence of noise on the pulse oscillations from a gain-switched multimode semiconductor
laser using multimode semiconductor laser rate equations that include Langevin noise. We found
that in the multimode oscillation, the Langevin noise suppressed the timing jitter and disturbed the temporal
synchronization of the pulse oscillations. By numerically estimating the output energy in the THz
time-domain spectroscopy, the degree of the temporal synchronization was estimated to be 95.5%.
