The purpose of the book is to show how general principles can be used to win insight into laser processes. The principles used may come from principal physical theory or from direct observation of >experimental results, but one understanding of the general characteristics of the behaviour of a procedure is essential for intelligent investigation and implementation, whether the approach is experimental, observational, numerical or analytical. The last two have a special prize since the associated costs can be relatively low and may subsist used as a starting point for more expensive techniques. The version of simple models whose underlying principles are easy to see is on that account of special value, and an understanding of their strengths and limitations is rudiment.
The applications considered in detail are cutting, keyhole welding, drilling, arc and hermaphrodite laser-arc welding, hardening, cladding, forming and cutting, but the captain-~ principles have a very wide application; metallurgical aspects are considered, during the time that are femtosecond interactions with metals. The book begins with a debate of the mathematical formulation of some relevant classes of physical ideas, and ends through an introduction to comprehensive numerical simulation. Although all the examples considered have the common feature that the source of power is a laser, people of the principles and methods apply to thermal modelling in a diversity of different fields and at many different levels of power.
