Abstract
Light pulses 0.3-nsec wide were generated from a mode-locked Nd-glass laser which had its bandwidth narrowed by spectral-mode selectors. The duration of these pulses, as measured by the two-photon fluorescence technique, corresponded to the inverse bandwidth in the frequency domain as measured with a Fabry-Perot interferometer. A fast rise-time light detector showed that more than half of the modes were phase locked.
