There are many intriguing possibilities for both basic research and real-world application presented by organic nonlinear optics. Similar to other high-tech industries like microelectronics and genetic engineering, technological and scientific developments will probably interact fundamentally in a way that fosters advancements in the other. For instance, optical and laser technologies are increasingly using nonlinear optical phenomena. Since photonics has such a wide range of potential application technologies and each has its own specific requirements, the process of optimizing materials for third-order nonlinear optical applications is difficult, and no single solution is likely to emerge as dominant. For instance, nonlinear optical phenomena-based optical systems are increasingly utilised in practical applications. It necessity in order to evaluate the nonlinearity of the optical characteristics of freshly created materials is growing as nanotechnology develops and new nano-materials with specific attributes are created. The operation of optical components in systems with powerful laser sources requires nonlinear refraction and absorption of optical materials, including biological materials. This, as well as the advancement and enhancement of laser technology, necessitates an increase in the precision and automation of techniques for studying optical nonlinearity in materials. In practice, certain approaches are employed to investigate one or more nonlinear effects. One of these approaches, Z-scan methods, is particularly well adapted for the simultaneous study of two nonlinear processes, nonlinear absorption and nonlinear refraction, both of which relate to the dielectric permeability of materials. This technology is modified in two ways: open aperture Z-scan for studying optical nonlinear absorption and closed Z-scan for studying material nonlinear refraction.
