NONLINEAR OPTICAL PHENOMENA OBSERVED IN LIQUID CRYSTALS 

In Table 12.1, we list the effective nonlinear index coefficients 2 of these NLC materials along with other well-known classes of nonlinear optical materials 1. Note that is the equivalent third-order nonlinear susceptibility ot is the absorption 

For practical apphcations, the absorption constant and response times of the material have to be taken into account by defining a figure of merit termed the switching efficiency The typical values for these materials are listed in Table 12.2. One
