(Color online) as a function of at delay. From bottom to top the applied laser fluence is increasing from 300 (⊕), 375 (▴), 490 (∎), 560 (⋆) to (엯). The uppermost line is the static differential for pure water. The dips marked by the arrows are caused by the disappearance of Bragg scattering.
(a) Simulation of the SAXS part , which is weighted by with the modeling of the core-shell structure together with the size reduction of the core particles. (Solid line: full calculation; dashed line: only the contribution from size reduction) (b) Comparison of the bubble radius from LS (엯) with the SAXS fits (∎). At a fluence of the first signature for bubble formation occurs, no bubbles are detected below that threshold (◻).
Bubble radius and pressure transients of the water vapor inside the bubbles as calculated from the Rayleigh-Plesset equation together with the measured radii. The first maximum in pressure at marks the collapse of the bubbles, the following modulations are only expected for oscillatory bubble motion.
