“…The pure magnitude of the NLR obtained to be as (0.138×10 -5 cm 2 /mW). The obtained results are compared with other results for different liquid crystal subjects [8][9][10][11][12][13] and shown in table (1). It was observed that our study is a convergence with most of these materials and a distance with others by calculating Absolute Error (AE) for these previous results utilizing the NLC program, Figures (7), and (8).…”

In this work, non-linear optical properties of a Sony SVGA liquid crystal spatial light modulator sample are estimated by utilizing a single beam Z-scan technique with He-Ne laser at 632.8 nm. It was found that the magnitude of non-linear refractive index (NLR) is (0.694×10 -7 cm 2 /mW) with a positive signal, demonstrates a self-focusing phenomenon, while the magnitude of non-linear absorption (NLA) for this sample is (0.0101×10 -1 cm/mW), the pure magnitude of the NLR is (0.138×10 -5 cm 2 /mW). These results are compared with past investigations in various liquid crystals types. The obtained results showed that the sample have a high ability of originating optical limiters, switches, and modulation gadgets.
