Polarization of optical echo in Pr3+:LaF3
Lisin V. N.
Echo signals are calculated with allowance for the mechanism for electric dipole transitions, the local symmetry of the ion site in the crystal, and the crystal structure. The echo polarization is governed by simple rules selecting optical transitions. It is equal to the sum of three vectors which are directed along three crystallographic axes, respectively. The relative magnitude of each vector depends on only the areas under the laser pulses and the orientation of the pulse polarization with respect to the corresponding axis.
