Chapter 4 Stimulated Scattering Effects of Intense Coherent Light
This chapter discusses the development and progress of stimulated scattering studies over the past four to five decades. The chapter focuses on the principles (mechanisms or models), basic experimental features, and technical applications of various stimulated scattering effects and related processes. Stimulated scattering is a very broad research subject. The key issues of the impulsive stimulated (Brillouin, Raman, and thermal) scattering studies are focused on the dynamic responses of short (or ultrashort) laser pulse-induced phonon fields. In a similar manner, studies of stimulated scattering in plasmas are mainly aimed at exploring opto-physical properties of the plasma medium. Other stimulated scattering-related issues, such as the CARS effect is a Raman-enhanced four wave frequency-mixing (FWFM) process, which requires phase-matching condition and can only occur in the forward direction.
