Accelerated expansion of laser-ablated materials near a solid surface

This paper demonstrates the effect of dynamic source that accelerates the unsteady expansion front in the direction perpendicular to the target surface significantly faster than predicted from conventional methods. The related effect of dynamic partial ionization that increases the expansion in all...

Description
Summary:	This paper demonstrates the effect of dynamic source that accelerates the unsteady expansion front in the direction perpendicular to the target surface significantly faster than predicted from conventional methods. The related effect of dynamic partial ionization that increases the expansion in all directions is also studied. The results may help explain the problem of high expansion front velocities observed in laser-ablation experiments without introducing more complex mechanisms.
