Fundamentals of Lasers

This section gives a short introduction to the basic physics of lasers in a more intuitive than mathematical way. A more detailed treatment of laser physics and an extensive discussion of various types of lasers can be found in textbooks (see, for instance, [5.1-5.10]). For more advanced presentations based on the quantum-mechanical description of lasers, the reader is referred to [5.11-5.15].

For several sections of Vol. 2 some basic knowledge of spectroscopic techniques or instrumentation is necessary. Therefore, cross links to Vol. 1 are given, where the fundamentals of laser spectroscopy are discussed. 

Laser is a recent innovation in rework and repair. The fundamentals of laser for initial soldering or for repair have already been discussed in Chap. 47. In the commercial incarnation of this technique, a laser beam is quickly scanned around component leads or, package surface, in the case of area-array devices such as EGAs and chip-scale packages (CSPs). It is most effective for plastic packaged components rather than the thermally massive CBGAs, CCGAs, and so on. In this technique, the component body is heated. Otherwise, there is little difference between this and alternative rework or repair techniques. 

Chapter 5 is a short recapitulation of the fundamentals of lasers, such as threshold conditions, optical resonators, and laser modes. Only those laser characteristics that are important in laser spectroscopy are discussed here. For a more detailed treatment the reader is referred to the extensive laser literature, for example [1.1-5].
