Over the past decades, study of nonlinear optical properties of materials has been one of the major research topics in the field of Nonlinear Optics (NLO). Nonlinear optical materials are used for various optoelectronics applications such as optical switching, optical computing, optical data storage devices, optical phase conjugation and optical limiting, etc. Optical Limiting (OL) is one such important application in which the transmittance of laser beam through the materials decreases with increase in input intensity. Optical limiting materials are used to protect the human eyes and optical...
