Summary: It has been found that adjusting the target prior to laser-target interaction can significantly enhance the coupling efficiency between laser pulses and the target, leading to the generation of high-energy electron-positron pairs. This has important implications for applications in nuclear photonics, material science, and astrophysical processes modeling.

Summary: This study presents a rational design strategy to protect photoinduced carbonyl free radical emission through electrostatic interaction and spin delocalization effects. A host-guest system consisting of tricarbonyl-substituted benzene molecules and imidazolium ionic liquids was constructed, enabling in situ generation and stabilization of carbonyl anion radical emission. The luminescence efficiency was significantly influenced by the anion species and alkyl chain length, with the highest radical emission efficiency being four times higher than a polymer-protected radical system. Theoretical calculations confirmed the synergistic effect of electrostatic interactions and spin delocalization in stabilizing the radical emission.

Summary: This paper introduces a method to distinguish neoplastic tissues from non-neoplastic tissues using calibration-free laser-induced breakdown spectroscopy (CF-LIBS). By analyzing the plasma emission lines of different elements, the study identified higher concentrations of major and trace elements in neoplastic tissues, especially in the early temporal observation windows. The results obtained from the CF-LIBS method were in good agreement with that of Inductive coupled plasma-optical emission spectroscopy (ICP-OES).

Summary: This study reports for the first time significant wavelength down-conversion caused by FWM in a Ytterbium/Raman random fiber laser, as well as the simultaneous observation of nonlinear optical dynamics of SRS, FWM, and self-pulsation. The experimental results agree well with theoretical calculations for the FWM process, highlighting the importance of these findings for high power Raman-based fiber lasers and random fiber lasers.

Summary: In this study, highly bright and photostable membrane-mimetic 2D nanosheets were designed and synthesized from sequence-defined peptoids, showing high quantum yield and photostability due to the precise placement of dye molecules. These nanosheets were utilized as biocompatible and programmable probes for live cell imaging and cell labeling, with the potential for enhanced lysosome escape and efficient intracellular delivery of macromolecular drugs by programming different surface charges.

Summary: The efficiency of using silicon nanoparticles produced by laser ablation of porous silicon in liquids for hyperthermia of tumours with laser radiation at wavelengths of 633 and 800 nm is evaluated. Numerical modelling of heating tumour tissue with embedded nanoparticles shows an increase in maximum temperature of 0.2-4 degrees C compared to heating without nanoparticles, depending on irradiation wavelength and intensity.

Summary: One-dimensional periodic surface structures were fabricated on amorphous hydrogenated silicon films by femtosecond laser irradiation. The orientation of the surface structure is determined by laser polarization and the concentration of excited carriers, affecting the formation of periodic relief. Femtosecond laser irradiation significantly increases the conductivity of the films by inducing the formation of Si nanocrystalline phase.

Summary: This study reports the circular anisotropy of third-harmonic generation in an array of silicon nanowires, demonstrating the manifestation of the photonic spin Hall effect mediated by the special guided-like mode structure in each SiNW. Experimental results show significant dependence of the third-harmonic signal on the polarization state of incident radiation and the spatial orientation of the SiNW array.

Summary: The possibility of manufacturing silicon nanoparticles by picosecond laser fragmentation of silicon microparticles in water is analyzed. The average particle sizes are found to have a nonmonotonic dependence on the initial mass concentration of the micropowder. Simulations show that fragmentation occurs in different regions depending on the concentration, with deeper propagation resulting in fragmentation in the paraxial region while higher concentrations lead to surface fragmentation due to strong extinction. Spectrophotometry measurements indicate the potential use of these fragmented nanoparticles in optical imaging of biological objects.

Summary: Biodegradable and low-toxic silicon nanoparticles (SiNPs) show potential in biomedical applications, particularly in tumor hyperthermia. The optical properties and effectiveness of SiNPs in laser tumor hyperthermia are influenced by their synthesis method and solvent. Laser ablation of silicon nanowires in ethanol produces SiNPs with better heating effects for tumor hyperthermia, while those synthesized in water provide stronger shielding against laser irradiation.
