Optical nonlinearity in a silver-decorated reduced graphene oxide-molybdenum disulfide (Ag-rGO-MoS) nanocomposite was experimentally investigated the -scan technique using a Q-switched Nd:YAG nanopulsed green laser. An interesting switching behaviour from saturable to reverse saturable absorption with varying input on-axis intensity of the laser was demonstrated. Under low-intensity laser excitation, Ag-rGO-MoS displayed ground-state bleaching, which resulted in saturable absorption (SA) behaviour.

Transition metal molybdates have garnered attention in the nonlinear optics field due to their outstanding optical and luminescent properties, which give rise to widespread applications in next-generation optoelectronics devices. The structural confirmation of the as prepared silver molybdate nanoparticles were made by XRD and Raman spectroscopy analysis.

This research work focuses on the synthesis and characterization of p-toluidinium 2,4-dichlorobenzoate (PTDA), organic non-linear optical crystal grown at room temperature. Single crystal X-ray diffraction (SCXRD) analysis was used to analyze the lattice parameters under the centrosymmetric space group of P121/c1 with a monoclinic crystal system. The crystalline nature and phase identification of the sample was analyzed by powder X-ray diffraction (PXRD) analysis.
