“…Because of nucleation, advancement & cluster formation, it is a subordinate to the bottom-up process. Interacting with ultrashort laser beam pulses i.e., 13 8 10 10 sec −− to , generates nanostructures from the metal bulk substrate in any medium, is called a laser ablation process [32,50,51]. It depends on aspects like laser wavelength (λ), repetition rate, frequency, pulse duration, the light absorption efficiency of material, transmission, and chemical composition of the liquid.…”
