AB  - The study deals with morphological effects on the silver target irradiated with ultrashort laser pulses in liquid (water). Synthesis of metal nanostructures (NS) by laser ablation in liquid is a relatively new method with benefits including clean production, without the use of additional chemicals necessary in conventional techniques, obtaining of pure particles with no surfactants, and good stability of the colloid. There are fewer studies, however, concerning the effects on the target itself during the laser action, and this type of research could lead to a better understanding of the physics involved and therefore better control of the process by linking the induced morphological features with NS synthesis results – yield, size distribution, etc. Also, reports on the laser ablation parameters of silver in liquid environment are scarce and significant for every particular set of parameters (laser pulse length, other laser parameters, liquid type). In this work, Ag target was irradiated with laser pulses 40 ps long, at 1064 nm wavelength and 10 Hz repetition rate. Irradiation time was 5 min, and pulse energies ranged from 0.5 mJ to around 22 mJ. Submicron particles were synthesized for all energies above 1 mJ and their size varied from tens of nanometers to ~200 nm. Optimum results were obtained for energies ~14- 17 mJ. Ablation depths were in the range of 30 to 100 µm for the above mentioned energy range. Damage threshold fluence was determined to be around 0.7 J/cm2 . Surface features were distinctly different than in air with sponge-like structure.
