The transmittance of a crystal can be expressed in terms of the photon's Green function (GF), solved by the equation of motion method for the GF and evaluated numerically. In the particular case of absorption of two phonons by an anharmonic crystal the formulae are derived for the, self energy of the photons and then for the transmittance of the crystal.
