The change of polarization of the resonant Raman scattering lines is studied in CuGaxAl1-xS2 crystals with x equal to 1, 0.95 and 0.9 assuming resonance conditions with 4880 and 4765 Ar laser lines. Linear and circular depolarization of the emission under the excitation by polarized light is observed. The depolarization of LO-phonon resonance Raman scattering (RRS) lines is found to occur practically in the same way for phonons with different symmetries. This observation is explained by the participation of polaritons in the processes of RRS as initial and final states. |
