SELECTION AND AMPLIFICATION OF A SINGLE MODE-LOCKED OPTICAL PULSE

Abstract
A single pulse was selected from the train of mode‐locked pulses of a Nd‐glass laser using optics external to the oscillator cavity. Its pulse width was measured by the two‐photon fluorescence technique to be 10 to 15 psec with and without amplification. From energy measurements, the amplified single‐pulse power was determined to be typically 30 GW.
