Chapter 8 Spontaneous Light Scattering and Acoustooptics
8.1. Features of Spontaneous Light Scattering
In this chapter, we describe spontaneous light scattering; Chapters 9 and 10 present descriptions of various stimulated light-scattering processes. By spontaneous light scattering, we mean light scattering under conditions such that the optical properties of the material system are unmodified by the presence of the incident light beam. We shall see in the following two chapters that the character of the light-scattering process is profoundly modified whenever the intensity of the incident light is sufficiently large to modify the optical properties of the material system.
Let us first consider the light-scattering experiment illustrated in ...
