Laser ablation of aluminum target by single and double pulse (∼ 5 ns delay) in ambient air and distilled water Comparing with air, in ambient water, plasma confinement results in higher crater depth. In comparison with single pulse laser ablation, the absorption of the laser pulse energy is higher for double pulse regime. As a result of ablated material expansion, the crater depth is decreased if the target is placed at lower depth.
