• generated using nanosecond IR lasers [41]. A direct size comparison of naproxen and fenofibrate particles generated by nanosecond and femtosecond lasers showed that shorter pulse durations favor the generation of smaller NPs, analogous to the dye studies described above. However, in addition to laser

• oscillating in the UV [18] but more often by femtosecond lasers [15][16][17][22]. Nanosecond laser irradiation has rarely been reported as a source of metal reduction in glasses [23]. The studies cited indicated that the performance, i.e., the optimal process conditions, depends strongly on the glass type and

• ]) since the photon energy at this time-scale is transferred to the electrons in the gold nanoparticle and diffusion is minimized [39][40]. The gold nanoparticles therefore retain their optical properties during LIB with pulses shorter than 10 ps. Compared to femtosecond lasers, ultrashort picosecond

The second strategy involves direct PLAL from the corresponding alloy targets [28][139] an approach adapted to fabricate AuAg alloy nanoparticles in a flow-through

Therefore, the DPP etching process cannot be attributed to conventional multi-photon excitation processes [36]. A comparison of atomic force
