Evolution of far-Field Diffraction Patterns and Nonlinear Optical Properties of SAE 70 Oil
Journal Title: International Journal of Applied and Natural Sciences - Year 2017, Vol 6, Issue 4
Abstract
The investigation of nonlinear optical characteristics of SAE 70 oil, by using self - diffraction techniques and Z-scan technique, using continuous wave (CW), visible laser beam is presented. Multiple diffraction rings were observed, when a beam propagates through this oil. A large thermal-induced nonlinear refractive index, up to 2.498 ×10−7 cm2/W was obtained from SAE 70 oil, under 473 nm continuous wave (CW), laser irradiation. The nonlinear absorption of SAE 70 oil was obtained from open aperture, z-scan technique. Optical limiting performance of SAE 70 oil was investigated under irradiation, by a CW laser beam using transmission measurement, through the sample which indicates that this material is a potential candidate, for optical limiting applications in low power CW regime.
