The study of the nonlinear optical properties of solutions under CW laser illumination

الملخص EN

The nonlinear optical properties of Janus green in tetrahydrofuran solvent (THF) were studied using single beam Z-scan technique with a continuous-wave laser radiation at 635 nm of an output power of 40 mW.

All the solution samples showed large nonlinear refractive indexes and absorption coefficient of the order of 10-7 cm2 / W and 10-3 cm / W, respectively.

The concentration-dependent nonlinear refractive index was also investigated.

The solvent of spectroscopic grade and was used without further purification.

All the solutions used for the study were freshly prepared.
