“…Due to their wide range of applications in optical and photonic devices, such as optical limiting (Marbello O et al 2020), optical switching (Henari and Cassidy 2012), and optical communication (Wong et al 1991), most researchers are currently concentrating on exploring materials with high non-linear optical responses. On the other hand, studying non-linear optical properties ensures sample authenticity and purity (Ribeiro et al 2019) and sample differentiation (de Souza et al 2020). Several methods are currently available to determine the non-linear characteristics of materials, including elliptical rotation, the measurement of beam distortion, interference of two or four waves, Z-Scan, and Spatial Self Phase Modulation (SSPM) (Li 2017).…”

The non-linear optical responses of cherry seed oil, avocado seed oil, and sesame oil were studied by observing spatial self-phase modulation (SSPM) in oil samples using a continuous wave laser beam. The non-linear refraction coe cients and third-order non-linear susceptibility of edible oils were estimated to be and , respectively, based on the intensity-dependent number of observed symmetric diffraction rings. Also, we examined the spatial self-phase modulation technique to investigate the authenticity of three adulterated oils based on their non-linear optical properties. For this purpose, ve different adulterated samples were prepared by diluting samples with sun ower oil (cheaper commercial oil) in various dilution ratios. The measured non-linear optical parameters of adulterated samples revealed that the non-linear optical parameters of diluted oils correlate strongly with the samples' levels of adulteration. The results suggest that the SSPM technique might be considered for estimating the degree of adulteration of samples based on their non-linear optical responses.

“…The importance of the design of optical devices, such as modulators and switchers, has also led researchers to discover and introduce new materials that can be used to advance the fields of photonics and communications [4][5][6][7]. On the other hand, the utilization of NLO responses has recently gained prominence as a viable approach to authentication and fraud detection in various materials [8,9]. In general, optical nonlinearity is associated with changes in material properties, such as the refractive index and absorption coefficient, caused by exposure to high-power light [10].…”

“…These methods require advanced and expensive equipment to prepare and ship the samples for testing. Studies presented by Ribeiro et al [9], de Souza et al [32], and Hassan et al [8] show that studying the NLO properties of materials offers an accessible and novel approach in this field. As a result, the presence of NLO phenomena in any given food sample provides the ability to perform authentication via evaluation of NLO parameters.…”

The nonlinear optical (NLO) response of materials is the basis for their use in various applications, including optical switching, optical data storage, and optical limiting. Additionally, it can be used as an innovative method of authentication. In this study, the NLO properties of virgin cherry kernel oil (VCKO) were studied through the observation of spatial self-phase modulation (SSPM) diffraction rings using a 532 nm continuous-wave laser beam. Based on the intensity-dependent number of symmetric diffraction rings, the nonlinear refraction coefficient and thermo-optical coefficient of VCKO were estimated to be 3.81×10-6 cm2/W and 5.34×10-4 K-1 , respectively, for the first time according to the authors' knowledge. Furthermore, we employed the SSPM technique for adulteration detection in the VCKO by analyzing its NLO properties. To accomplish this, we prepared different adulterated samples by mixing VCKO with cheaper commercial oils such as virgin sunflower oil (VSFO) and virgin canola oil (VCO) at various concentration ratios. In mixed VCKO samples that were adulterated, the measured NLO parameters were correlated highly with the amount of adulteration. The results confirm the ability of the SSPM technique to determine the degree of adulteration in oil samples by measuring and comparing their NLO properties. In addition, our results indicate that cherry kernel oil can be a viable candidate as a nonlinear medium for optical applications.

The non-linear optical responses of cherry seed oil, avocado seed oil, and sesame oil were studied by observing spatial self-phase modulation (SSPM) in oil samples using a \(405\,nm\) continuous wave laser beam. The non-linear refraction coefficients and third-order non-linear susceptibility\({\chi ^{\left( 3 \right)}}\)of edible oils were estimated to be \({10^{ - 6}}\,c{m^2}/W\)and\({10^{ - 5}}\,esu\), respectively, based on the intensity-dependent number of observed symmetric diffraction rings. Also, we examined the spatial self-phase modulation technique to investigate the authenticity of three adulterated oils based on their non-linear optical properties. For this purpose, five different adulterated samples were prepared by diluting samples with sunflower oil (cheaper commercial oil) in various dilution ratios. The measured non-linear optical parameters of adulterated samples revealed that the non-linear optical parameters of diluted oils correlate strongly with the samples' levels of adulteration. The results suggest that the SSPM technique might be considered for estimating the degree of adulteration of samples based on their non-linear optical responses.
