Stimulated Orientational Scattering and Polarization Self-Switching Steady State

Stimulated Orientational Scattering and Polarization Self-Switching Steady State 

Earher observation of transient SOS effects was conducted in the spirit of stimulated Brillouin scattering and involved fairly high power pulsed ruby laser. However, 

NONLINEAR OPTICAL PHENOMENA OBSERVED IN LIQUID CRYSTALS 

Since the two-beam coupling effect depends only on the frequency difference between the pump beam and its scattered noise, the conversion process should hold whether it is from e to o waves, or o to e waves. By repeating the same experiments with an o-wave input (rotating the planar nematic sample by 90°), similar stimulated e-wave scatterings have been observed at similar laser power levels (see Figs. 12.10a and 12.10b). 

For fundamental studies, these polarization self-switching processes could also be integrated into the spatial soliton formation discussed in the previous section, and thus a host of novel optical phenomena await the inquisitive.
