Abstract
The polarization dependence of three- photon absorption in solids is developed using the Wigner- Eckart theorem for finite symmetry groups. The expression for the absorption coefficient is separated into two parts:
1) The geometrical part, which depends on the polarization vectors of the three photons.
2) The dynamical part, which contains the product of three electron- photon matrix elements.
New information can be gained by studying these two parts. An application to TICI crystal is given and an experimental method is suggested.
