Nonlinear optical and thermo-optical properties of two pure ionic liquids, BMIOMe.NTf2 and BMIOMe.N(CN)2, were examined here. It was the first nonlinear refractive index determination of a pristine ionic liquid by a standard self-refraction experiment. The nonlinear optical characterizations were performed using Z-scan and EZ-scan techniques in the thermally managed approach with a mode-locked femtosecond laser source. Thermal properties were analyzed concomitantly and the thermo-optical coefficient, thermal characteristic time, and lens strength were characterized. These results show that BMIOMe.NTf2 is a prominent material to be engineered for photonics applications
