Summary: The laser-induced periodic surface structure (LIPSS) can be induced on the 4H-SiC by femtosecond laser, but there are some problems during the laser process, such as debris dropped on the sample surface. In this study, high-spatial-frequency LIPSS (HSFL) were generated on the 4H-SiC surface using femtosecond laser. Raman spectrum was used to measure HSFL and chemical etching removed the oxidation layer. The results showed a strong correlation between the Raman intensity of amorphous SiC (a-SiC) and the etching rate of HSFL. Additionally, high-quality periodic structures were generated on 4H-SiC after the chemical etching process, with two different morphology observed by transmission electron microscope (TEM).

Summary: S-doped black silicon directly processed in ambient air by femtosecond laser irradiation exhibits high absorption over a wide spectral band from visible to infrared. The introduction of SiO2 due to the passivation effect increases the valent state ratio and reduces background free carrier concentration and complex structural defects, leading to improved lifetime of photo-generated carriers and enhanced thermostability. The metal-semiconductor-metal infrared photodetector based on S-doped black silicon shows superior photosensitivity, outperforming unprocessed Si under the same conditions.

Summary: Micro-opto-electromechanical systems (MOEMSs) are a new class of integrated and miniaturized optical systems with significant applications in modern optics. This study proposes a femtosecond-laser-assisted dry etching technology for fabricating silicon microlenses, where the size of the microlens can be controlled by the laser pulse energy and number of pulses. The integration of multifocal microlens arrays into a silicon microcantilever using this method broadens the application scope of MOEMSs in three-dimensional imaging systems.

Summary: Ultrashort electron beams generated through tight focusing of femtosecond infrared lasers in ambient air present a unique opportunity for studying ultrafast structural dynamics and ultra-high dose-rate radiobiological studies. These electron beams can reach up to 1.4 MeV at a dose-rate of 0.15 Gy/s, providing enough dose rate for radiation therapy applications. The acceleration mechanism is based on the relativistic ponderomotive force, as confirmed by 3D Particle-In-Cell simulations. The scalability of this method and its potential for FLASH radiation therapy is discussed.

Summary: In this study, the ultrafast thermalization dynamics of temperature fields in Au/Ni film excited by a femtosecond laser double-pulse vortex beam were theoretically investigated. It was proposed that the energy deposition in the layered film can be significantly enhanced by applying the double-pulse vortex beam, leading to vortical thermalization in the Ni layer on a picosecond timescale. The intensified dynamics of the double-pulse vortex beam interacting with the excited state of the film and the energy competitive processes of electron diffusion and electron-phonon coupling were identified as the main causes for this phenomenon. The research also explored the relationship between the electron-phonon coupling period of the film and important laser parameters such as pulse separation and vortex beam fluence.

The study revealed two forms of salt precipitation - aggregated polycrystalline structures and large bulk crystals. It was found that gas bubbles could form due to liquid imbibition into aggregated polycrystalline structures. The length of a corner liquid film affected the growth direction of the aggregated polycrystalline structures.

Summary: We theoretically investigate the spatial-temporal dynamics of extraordinary optical transmission (EOT) in a two-slit plasmonic antenna irradiated by femtosecond laser dual-beam. The dynamic interference of femtosecond laser dual-beam with transiently excited surface plasmon polariton waves is proposed to characterize the specific spatial-temporal evolutions of EOT. Our study reveals that the dynamic EOT can be flexibly switched and its symmetry can be tunable by manipulating the phase correlation of the crossed femtosecond laser dual-beam. Furthermore, we obtain the unobserved traits of symmetry-broken transient spectra of EOT from the respective up- and down-slit of the antenna.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
