“…However, as far as we know, no studies have been conducted on the NLO response of virgin cherry kernel oil (VCKO) with a 532 nm laser beam wavelength; this paper fills that gap. The high NLO response observed in vegetable oils is attributed to their substantial dielectric properties and the presence of conjugated double bonds [15,16]. Vegetable oils typically have high dielectric properties owing to the presence of fatty acids and other lipid components [17].…”

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.

Oils of vegetable origin are classified as organic compounds, which have become the object of study in the field of photonics and non-linear optics, because they have a characteristic chemical bond with the presence of delocalized electrons, which gives them a high non-linear response. In the food industry, non-destructive or invasive studies are required to establish the quality and conservation indices of the chemical, physical and nutritional properties of edible products. The non-linear optic response of different oils of vegetable origin was evaluated: extra virgin olive oil, extra virgin sesame oil, extra refined linseed oil and virgin avocado oil using the Z-scan technique. The absorption and transmission spectra were taken to establish the coefficient of linear absorption of the sample as a function of the wavelength. For each compound, the variations of the nonlinear optical properties were analyzed as a function of the excitation power, using the closed cell and open cell configurations; where the third-order electrical susceptibility (χ 3), the non-linear refraction index (η 2) and the non-linear absorption coefficient (β) were determined. Subsequently, a comparison of the non-linear response was made according to the type of oil and the degree of refinement. It was found that extra virgin olive oil and virgin avocado oil presented a better non-linear response at low laser power as a consequence of the low thermal influence, which makes them possible candidates in the development of photonic devices.
