AB  - In a linear medium, the index of refraction and the absorption coefficient are independent of theintensity of light, the frequency of the light does not change in the medium, the frequency depends only on thesource, the principle of overlap applies, Light and light cannot be controlled (photon-photon interaction does notoccur). In the non-linear environment; The refractive index depends on the intensity of the light, the frequencychanges, the overlap principle does not apply, the light can be controlled by light. Non-linear optics has manyapplications and these applications are becoming more common every day. Some of these applications areoptical switching, hologram, laser physics, optical communication. The differences can be explained by theshape of the laser pulse and its deviation from the theoretical form, which is often difficult to determine.Another factor affecting the accuracy of measurements of nonlinear parameters of materials is the uncertainty oflaser power measurements and the waist size of the focused beam, deviations from the Gaussian distribution,inhomogeneity of the studied material, etc. Linearity is a property of the medium, not the light. It cannot beobserved in the absence of nonlinear optical matter (empty space). By changing the properties of the medium,the light causes the properties of the light passing through this medium to change, even its own properties. Ahigh-power light source may have different energy (frequency) values as it passes through the material it passesthrough. If the value of the applied external electric field (E) is large enough (high energy intensity light isused), the polarization vector will also include non-linear effects. CS2 is accepted standard test material for nonlinear measurements by scientists interested in nonlinear optics. Some applications of CS2 is fumigation,insecticide, solvent, manufacturing, health effects.
