“…In this hot core region, a nearly neutral vapour is ejected forming a thin vapoor layer above the target surface [ 35 – 39 ]. The subsequent plasma generation takes place via optical breakdown, which is favoured by a large density of free electrons from the initially laser-generated vapour [ 35 , 36 , 40 ]. The electrons ejected from the surface originate either from the photoeffect and those formed due to the ionization of atoms.…”

We report on the properties of laser-induced plasma plumes generated by ns pulsed excimer lasers as used for pulsed laser deposition to prepare thin oxide films. A focus is on the time and spatial evolution of chemical species in the plasma plume as well as the mechanisms related to the plume expansion. The overall dynamics of such a plume is governed by the species composition in particular if three or more elements are involved. We studied the temporal evolution of the plume, the composition of the chemical species in the plasma, as well as their electric charge. In particular, ionized species can have an important influence on film growth. Likewise, the different oxygen sources contributing to the overall oxygen content of an oxide film are presented and discussed. Important for the growth of oxide thin films is the compositional transfer of light element such as oxygen or Li. We will show and discuss how to monitor these light elements using plasma spectroscopy and plasma imaging and outline some consequences of our experimental results.

“…Amoruso's paper also contains a number of useful references to previous experimental works. The group of Sysoev worked intensively in this area and suggested theoretical models for the target evaporation and ion generation by laser shots (Kon'kova et al, 2009), for the processes of expansion of multicomponent plasma clouds (Sil'nikov et al, 2011) and for prediction of ion kinetic energy in such clouds (Kon'kova et al, 2012).…”

Laser ionization mass spectrometry (LIMS) was one of the first practical methods developed for in situ analysis of the surfaces of solid samples. This review will encompass several aspects related to this analytical method. First, we will discuss the process of laser ionization, the influence of the laser type on its performance, and imaging capabilities of this method. In the second chapter, we will follow the historic development of LIMS instrumentation. After a brief overview of the first-generation instruments developed in 1960-1990 years, we will discuss in detail more recent designs, which appeared during the last 2-3 decades. In the last part of our review, we will cover the recent applications of LIMS for surface analysis. These applications include various types of analyses of solid inorganic, organic, and heterogeneous samples, often in combination with depth profiling and imaging capability.
