WebJan 30, 2024 · Incoherent pulse regimes are nevertheless recurrent within ultrafast fiber laser dynamics. In this paper, we bring decisive experimental data, by recording in real time the buildup dynamics of incoherent pulses under different cavity dispersion regimes. Our measurements highlight different dominant mechanisms at play.

Temporal coherence is the measure of the average correlation between the value of a wave and itself delayed by τ, at any pair of times. Temporal coherence tells us how monochromatic a source is. In other words, it characterizes how well a wave can interfere with itself at a different time. The delay over which the phase or amplitude wanders by a significant amount (and hence the correlatio… WebNov 10, 2024 · The coherent part of the FLASH light generates the horizontal diffraction image with a few pronounced intensity maxima; the incoherent part generates the …
