By pumping a LiIO3 crystal with 1.06μm picosecond laser pulses train at a proper incident angle, 8 stimulated Raman scattering lines have been obtained at the visible region from 4896 A to 6119A:ω=2ω1±nωP, n = 1, 2, 3, concerned elementary excitations being LO mode and TO mode of (A+E1) oblique polariton in the crystal. The process of such a complex stimulated Raman scattering is as following: with phase matching intense 1.06?m laser beam and its scattering light generate SHG in the crystal; meanwhile it excites coherently the elementary excitations of the crystal，the latter scatter the SHG into Stokes and antistokes radiations resulting in a complex effect of and nonlinear optical process. Furthermore the reflected ward stimulated Raman scattering with distinct wavelength has been observed from the forward one. Present paper shows that the reflected ward scattering is also the SHG coherent Raman mixing but generated by the 1.06 μm beam reflected npon the exit crystal surface.
