Chapter 10 Stimulated Raman Scattering and Stimulated Rayleigh-Wing Scattering
10.1. The Spontaneous Raman Effect
The spontaneous Raman effect was discovered by C.V. Raman in 1928. To observe this effect, a beam of light illuminates a material sample (which can be a solid, liquid, or gas), and the scattered light is observed spectroscopically, as illustrated in Fig. 10.1.1. In general, the scattered light contains frequencies different from those of the excitation source. Those new components shifted to lower frequencies are called Stokes components, and those shifted to higher frequencies are called anti-Stokes components. The Stokes components are typically orders of magnitude more intense than the anti-Stokes components.
