Single picosecond light pulses from a mode-locked Nd:glass laser are investigated by several methods. Their temporal structure is studied by two-photon fluorescence. The frequency spectra are measured quantitatively. The energy distribution is simultaneously investigated by three-photon fluorescence, photoelectric measurements, and quantitative studies of the contrast ratio of the two-photon fluorescence. The pulse shape is measured using a method based on the stimulated Raman effect. It is observed that the pulses are weakly asymmetric-the pulse decay is slower (exponential) than the pulse rise (Gaussian). Bandwidth-limited pulses of 4-8 ps are present in the leading part of the pulse train. Substantial frequency broadening develops as the pulse train reaches its maximum and a subpicosecond structure is formed in the trailing part of the pulse train.read more

II Shaping and Analysis of Picosecond Light Pulses
TL;DR: In this article, the authors describe the shaping and analysis of picosecond light pulses and the space-time coherence effects due to the new situation arising in optics such as the circumstances when large amounts of energy are carried by every one of the space time modes of the radiation, a situation realized for example with the laser pulses.
