Lasers have been used for exciting applications more than any other scientific discovery of the last century. One important phenomenon intimately associated with lasers is the nonlinear optical characteristics of the materials which become pronounced and their realization seems realistic with intense laser sources. The nonlinear optical materials encompass a wide range of applications that create great impact on daily life. The fascinating applications of NLO include like 3D data storage devices, all optical switching devices, sensors, optical imaging, medicine, diversity of advanced lasers and coherent sources, military, and in scientific instrumentation etc. Due to their intriguing electrical and optical characteristics, two-dimensional (2D) materials have recently received a lot of attention. The non-linear optical properties of these materials could play a vital role in potential photonic applications, such as light modulation and optical limiting. Molybdenum disulfide (MoS2), an example of a two-dimensional (2D) layered material, is one of most sought-after material for improved nonlinear optical coefficients in addition to the advantages which it offers as it has potential uses in optoelectronic fields like phototransistors, optical limiters, and ultra-fast photonic devices because of its distinct layered structure. The nonlinear optical properties of pure MoS2, and its doped samples MoS2/rGO, Al-MoS2/rGO, and Co-MoS2 etc are examined thoroughly by employing the Z-scan technique. The surface morphology, structure, and the laser intensity are further discussed as factors affecting the NLO characteristics of these nanohybrids employing various analytical techniques, including X-ray diffraction (XRD), Raman spectroscopy, field-emission scanning electron microscopy (FESEM), and UV-Visible spectroscopy. The NLO properties of doped MoS2 nanohybrids are also compared with optical nonlinearity of multiferroic materials that attract a great attention of the researchers for fabricating new devices based on NLO materials and magneto electric coupling.
