Extended Data Fig. 3: Optical laser spot images.
From: Superheating gold beyond the predicted entropy catastrophe threshold
Images of the optical laser spots captured at the focal plane for the a, low fluence (1.9 ± 0.5 J/cm2) and b, high fluence (4.9 ± 0.5 J/cm2) cases. For the low fluence case, the laser spot has a FWHM of approximately 150 µm, while for the high fluence case, the FWHM is approximately 100 µm.
