Supporting data with code to generate Fig. 2 Cavity-induced deformation of a Gaussian input. Publication: DOI:https://doi.org/10.1103/PhysRevA.96.053820 arXiv:1710.02448 This dataset contains a zip file with raw data sets of all relevant measurements to plot figure 2. Figure 2. Envelope functions of the intracavity field for a 1 m cavity injected with a 1μs pulse for different cavity finesses. All areas are normalized to the input pulse area for comparison. When the pulse duration is comparable to the photon lifetime of the cavity, its envelope function is elongated. Inset: Envelopes without normalization.
