Measurement of the nonlinear optical properties of olive oil using Z-Scan

Abstract

A study of non-linear optical properties of extra virgin olive oil diluted in ethylic alcohol at different levels of concentration was made: 75% and 50%. The Z-Scan technique by transmission was used for the characterization of samples in closed settings, and it was also used as the excitation source an Nd-YAG laser emitting in 532nm. For the control of the technique was implemented an interface in LabVIEW that allowed us to visualized and control the development of the Z-Scan technique in real time. From the transmittance curves obtained was possible to calculate for each sample the non-linear refractive index. The obtained results show a variation of the non-linear optical properties of extra virgin olive oil when it is diluted in alcohol.

Universal Scaling in the Dynamic Hysteresis, and Non-Markovian Dynamics, of a Tunable Optical Cavity

“…To endow the cavity with a nonlinear optical response, we place olive oil inside [47][48][49]. Through z-scan measurements, we estimated the nonlinear refractive index n 2 of our oil to be ∼ − 5 × 10 −8 cm 2 =W at 532 nm, consistent with Ref.…”

“…Through z-scan measurements, we estimated the nonlinear refractive index n 2 of our oil to be ∼ − 5 × 10 −8 cm 2 =W at 532 nm, consistent with Ref. [49]. Figure 1 shows the transmitted intensity through our oil-filled cavity averaged over 70 cycles and at three laser powers.…”

Universal power law decay in the dynamic hysteresis of an optical cavity with non-instantaneous photon-photon interactions

“…To endow the cavity with a nonlinear optical response, we placed a drop of olive oil inside. Oils are known for their thermo-optical nonlinearities [46][47][48]. Through zscan measurements we estimated the nonlinear refractive index n 2 of our olive oil to be ∼ −5 × 10 −8 cm 2 /W at 532 nm, consistent with Ref.…”
