“…Only three years after the presentation of the first operable laser source, its suitability for materials processing applications was demonstrated by the fabrication of diaphragms with an inner diameter of some microns [10]. Since that time, the laser has established as a state-of-theart technology in different fields of materials processing and mainly material removal, commonly referred to as laser ablation.…”

In the last few years, the combination of laser irradiation with atmospheric pressure plasmas, also referred to as laser plasma hybrid technology, turned out to be a powerful technique for different materials processing tasks. This chapter gives an overview on this novel approach. Two methods, simultaneous and sequential laser-plasma processing, are covered. In the first case, both the plasma and the laser irradiation are applied to the substrate at the same time. Depending on the process gas and the discharge type, the plasma provides a number of species that can contribute to the laser process plasmaphysically or plasma-chemically. Sequential plasma-enhanced laser processing is based on a plasma-induced modification of essential material properties, thus improving the coupling of laser energy into the material during subsequent laser ablation. Simultaneous plasma-assisted laser processing allows increasing the efficiency of a number of different laser applications such as cleaning, microstructuring, or annealing processes. Sequential plasma-assisted laser processing is a powerful method for the processing of transparent media due to a reduction in the laser ablation threshold and an increase in the ablation rate at the same time. In this chapter, the possibilities, underlying mechanisms, performance, and limits of the introduced approaches are presented in detail.

“…It is told that Theodore Maiman called the first operating laser source he and his coworker Charles Asawa realized 60 years ago [1] a "solution in search of a problem". Merely three years later, first experiments have shown the broad range of possible applications for laser irradiation such as a tool in materials processing [2] or an excitation source in emission spectroscopy [3]. The latter application, laser-induced breakdown spectroscopy (LIBS) is thus one of the oldest laser applications and can be regarded as a very basic utilization of direct laser-matter interactions.…”
