We report the use of a mode-locked fiber laser in pulsed laser deposition (PLD) of yttria-stabilized zirconium oxide. The
fiber laser produces picosecond pulses with megahertz repetition rates at the wavelength of 1060 nm. We have investigated
the effects of the time delay and the physical overlapping of the consecutive pulses on the ablation thresholds and the properties
of the deposited films. Our results show existence of two distinct evaporation modes: (1) a single pulse evaporation mode
observed for low overlapping and long time delays between the pulses and (2) a high repetition rate evaporation mode for high
overlapping with short delays. The first mode is characterized by evaporation of nanoparticles and clusters and yields structured
films with high surface area. The second mode yields smooth films, with evaporation characteristics closer to those of thermal
evaporation than traditional PLD. 相似文献

Light can play: Irradiation causes dramatic changes in the shape of rigid-rod polymers incorporating azobenzene photochromes in the main chain. The embedded photoswitches act as hinges, which upon light-induced isomerization lead to reversible shrinking and stretching of the polymer backbone (see scheme), resembling light-orchestrated macromolecular accordions. 相似文献
