1. Raman and Brillouin Scattering
J. R. Leonard

2. Talk Outline Basic Idea
Distinction Between Raman and Brillouin Scattering
Instrumentation
Brillouin Theory and Example
Raman Theory and Examples

3. Basic Idea Light scatters of a solid emitting or absorbing a phonon.
Follows conservation of energy and momentum.
Ashcroft and Mermin

4. Sample Spectrum
H. Z. Cummins and P. E. Schoen, in Laser Handbook, edited by F. T. Arecchi and E. O. Schultz-Dubois (North Holland, Amsterdam, 1972), p. 1029

5. Distinction Two types of phonons, optical and acoustic.
Raman scattering measures optical phonons.
Brillouin scattering measures acoustic phonons.
Kittel

6. Raman Instrumentation
H. Z. Cummins and P. E. Schoen, in Laser Handbook, edited by F. T. Arecchi and E. O. Schultz-Dubois (North Holland, Amsterdam, 1972), p. 1029

7. Brillouin Instrumentation

8. Classical Look at Brillouin Scattering
Long wavelength limit allows lattice to be treated as a continuum.
Scattering is off moving lattice distortions (phonons).
Follows Braggs Law in the phonon’s reference frame.
Ashcroft and Mermin

12. Data Analysis - Diamond
Used the model to calculate elastic moduli of diamond.
Intensity of lines consistent with other’s calculation of elasto-optic constants.
