Another study investigated the thickness of the utilized liquid layer and assumed an optimal plasma and shockwave pressure in a specific liquid height [7]. In this high pressure reaction field, during laser ablation in liquids, a cavitation bubble forms which expands, shrinks, and collapses with time [8,9] and is presumed to affect material removal rate.…”
