Sharp atomic and ionic line spectra of excimer-laser-induced ablation plasmas of samples in liquids were observed. A new double-pulse technique employing quartz fibers facilitates spectral analysis of samples in liquids in which spectral lines normally are strongly broadened and quenched. The first pulse generates a cavitation bubble on the sample surface, which provides a gaseous environment for optical emission spectroscopy on the ablation plasma induced by a second pulse fired into the bubble.read more

Double pulse laser ablation and plasma: Laser induced breakdown spectroscopy signal enhancement
Valeri I. Babushok,Frank C. DeLucia,Jennifer L. Gottfried,Chase A. Munson,Andrzej W. Miziolek +4 more
TL;DR: In this article, a review of recent results of the studies of double laser pulse plasma and ablation for laser induced breakdown spectroscopy applications is presented, where the authors demonstrate that the maximum effect is obtained at some optimum separation delay time between pulses, which depends on several factors, such as the target material, the energy level of excited states responsible for the emission, and the type of enhancement process considered.

Applications of Laser-Induced Breakdown Spectrometry
TL;DR: In this article, a high-powered laser beam is focused onto a small area or spot of a solid surface, the temperature of the locally heated region rises rapidly to the vaporization temperature of solid material and an optically induced plasma, frequently called a laser-induced plasma (LIP) or laser-ablated plasma or laser spark is formed at the surface.

Optical and acoustic investigations of the dynamics of laser-produced cavitation bubbles near a solid boundary
TL;DR: In this paper, the dynamics of laser-produced cavitation bubbles near a solid boundary and its dependence on the distance between bubble and wall are investigated experimentally by means of high-speed photography with up to 1 million frames/s that jet and counterjet formation and the development of a ring vortex resulting from the jet flow are general features of the bubble dynamics near solid boundaries.
