Optical coherence of non-stationary fields

Individual pulses in pulse trains from, e.g., mode-locked lasers or supercontinuum sources are typically not identical and thus the train can be considered as a partially spectrally and temporally coherent ensemble of realizations.

The aim is to model the correlation properties of such pulse trains using the coherence theory of non-stationary fields, numerical simulations of supercontinuum generation, and experimental measurements with techniques such as frequency-resolved optical gating. The models for spectral and temporal coherence then allow one to simulate the results of interferometric and other experiments with pulse trains, and to optimize the experimental setups.
