ABSTRACT
In the last chapter, we discussed photorefractive materials as an example of nonlinear optical materials that can be used for low-power optical processing. Another class of materials that offers potential for low-power nonlinear optical processing is liquid crystals, which are more commonly used for everyday applications such as displays. In this chapter, we will investigate the nonlinear optical properties of liquid crystals, alongwith how they interact with incident Gaussian beams.
