• unlocking the potential of PLAL. Spatial and temporal beam shaping in material processing The spatial focusing of the laser beam on the sample directly influences the ablation efficiency and the quality of the produced NPs. The most widely used PLAL system in different laboratories around the world consists

• mechanism. While, in femtosecond pulses, due to their ultrashort nature, the energy is deposited instantaneously into the material. This enables non-thermal ablation, where ionisation and photomechanical effects dominate the material’s response [163][164]. The role of temporal beam shaping in PLAL In this
