The laser emission spectra of several vertical cavity surface emitting lasers, following pulsed laser excitation, have been measured with a temporal resolution of [lt]1 ps. With broadband excitation, emission was observed from multiple longitudinal modes when pumped well above threshold. The output-pulse decay times of modes located near the edges of the high reflecting zone were significantly shorter than the decay times of modes located near zone center. The zone-edge modes were not observed when narrow-band photoexcitation was used, indicating that broadband excitation results in seeding of the laser cavity.
