Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Multiple studies in ultrafast optics demonstrate that light pulses can indeed be compressed simultaneously in time and space to achieve extreme field intensities.

The analysis

The retrieved papers provide robust theoretical and experimental evidence demonstrating that optical and laser pulses can be compressed both temporally and spatially (spatiotemporal compression, lambda-cubed regimes, and coherent harmonic focusing). Papers 2, 8, and 10 explicitly discuss spatiotemporal compression and focusing mechanisms of light pulses.
