Semiconductor nanoparticles are significant for technological applications, particularly in photonics. The main purpose is the focus on exploring nonlinear optical (NLO) characteristic of pure NiO and doped nanopowders (NPs) with 5% Cu, Co Fe elements were synthesized via Co-precipitation method. study confirmed nanoscale structure materials through Co-precipitation, analyzed their linear characteristics, validated these characteristics using Field Emission Scanning Electron Microscope (FE-SEM) X-ray Diffraction XRD techniques. investigation utilized Miller's rule Fournier Snitzer's equation to precisely assess susceptibility, energy dispersion, z-scan data polarizable constituent density, while also examining impact substitution crystallite size parameters. To explore NLO properties nanopowders, Z-scan method a 532 nm Nd: YAG laser was incident powers P0 = 15, 20 25 mW. absorption coefficient refractive index determined by approximately ( $${10}^{-4}$$ ) $${10}^{-9}$$ ), respectively. At mW, CuNiO CrNiO NLR NLA reverse saturable reaction seen at 5.88 × 10−9and 5.40 10−9 m2/W 11.3 10−3 12.1 m/W quantities, In this study, given that measurement technique precise method, we calculate parameter $${E}_{d}$$ . Subsequently, utilizing relationships derived from WD, extract parameters such as $${\chi }^{1}$$ $$N$$ Furthermore, determining Urbach $${E}_{u}$$ , investigate correlation defects examine its influence parameters.The remarkable coefficients prepared highlight potential developing effective limiting devices safeguard eyes sensors harmful radiation laser.
