Sketch of the side view of the system setup. The right picture is the typical image of the dusty plasma liquid.
(Color online) (a) Plume emission intensity measured at delay and exposure interval from a pulsed laser ablating on a polystyrene particle in dusty plasma. (b) Temporal evolution of the spatial intensity distribution at various delays from . The inset shows the emission intensity curve at delay fitted with a Gaussian distribution function. The operating pressure is .
(Color online) (a) Evolutions of the plume diameter at different laser energies from .(b) Expanding velocity of the plume at different laser energies. (c) Evolution of the peak intensity at laser energy. The operating pressure is in the above runs. (d) Plume diameter vs background pressure at laser energy and delay.
(a) Typical image of dust particles showing the formation of dust cavity obtained at delay and exposure and laser energy. (b) Temporal evolution of the dust cavity diameter at laser energy and pressure. The inset shows the corresponding expanding velocity of the dust cavity. (c) Double logarithmic plot of the temporal dependence of the cavity diameter at different laser energies from at pressure. The inset shows the dependence of the cavity diameter and background pressure at and delay.
