Research Abstract |
We examined the effects of superposing an ultrasonic wave on laser-induced plasma and cavitation bubble in liquid-phase laser ablation. The integrated optical emission intensity form ablation plasma was enhanced at negative phase of the wave. The repetitive formation and collapse of the cavitation bubbles was driven at the same frequency as the ultrasonic wave. Additionally, we revealed that the production rate and the crystallinity of nanoparticles were enhanced by superposing the ultrasonic wave.
