Description
Laser processing of solid materials has been commonly performed in gas ambient. Having the workpiece immersed into liquid, having a liquid
film on it, or soaking the material with liquid gives several advantages such as removal of the debris, lowering the heat load on the
workpiece, and confining the vapour and plasma, resulting in higher shock pressure on the surface.
Introduced in the 1980s, neutral
liquids assisted laser processing (LALP) has proved to be advantageous in the cutting of heat-sensitive materials, shock peening of machine
parts, cleaning of surfaces, fabrication of micro-optical components, and for generation of nanoparticles in liquids. The liquids used
range from water through organic solvents to cryoliquids.
The primary aim of the book is to present the essentials of previous research
(tabulated data of experimental conditions and results), and help researchers develop new processing and diagnostics techniques (presenting
data of liquids and a review of physical phenomena associated with LALP). Engineers can use the research results and technological innovation
information to plan their materials processing tasks.
Laser processing in liquids has been applied to a number of different tasks
in various fields such as mechanical engineering, microengineering, chemistry, optics, and bioscience. A comprehensive glossary with
definitions of the terms and explanations has been added.
The book covers the use of chemically inert liquids under normal conditions.
Laser chemical processing examples are presented for comparison only.
