• visible light, such as water treatment and degradation of organic contaminants [10][11][12]. Among various synthesis techniques, laser-based methods, such as pulsed laser ablation in liquids (PLAL) and laser pyrolysis, stand out as clean, efficient, and surfactant-free routes for fabricating Ag@TiO2

• nanomaterials. These physical processes enable the direct formation of highly pure and well-dispersed nanoparticles from bulk targets without the need for chemical precursors or stabilizing agents. By fine-tuning laser parameters such as wavelength, pulse energy, and ambient conditions, researchers can tailor
