The backscattering spectra of a 500 nm thick gold film, which was excited near the 525 nm transverse localized plasmon resonance of its constituent, self-organized, vertically-aligned nanorods by normally incident 515 nm, 300 fs laser pulses with linear, radial, azimuthal and circular polarizations, revealed a few-percent conversion into Stokes and...

The interaction of an ultrashort laser pulse of sub-relativistic intensity with an innovative high-average-density targets consisting of numerous sub-microwires or sheets was examined. The research demonstrates the stochastic nature of high-energy electron production in complicated EM field in such targets where volumetric laser energy absorption o...

A novel, successful method of bactericidal treatment of pathogenic bacterial biofilms in vitro by laser-induced forward transfer of metallic nanoparticles from a polyethylene terephthalate polymeric substrate was suggested. Transferred nanoparticles were characterized by scanning and transmission electron microscopy, energy-dispersive X-ray and Ram...
Conference Paper
Full-text available
In experimental backscattering spectra of a gold film were found resonances which may reveal features of the film inner structure. The explanation of these features based on the analysis of the structure's unit cell and its response to laser radiation was proposed. 1. Introduction One of the possible methods for characterization of plasmonic films...
Article
The interaction of an ultrashort laser pulse of moderate intensity ( ≳ 10¹⁸ W/cm²) with an innovative high-average-density target consisting of numerous sub-microwires was examined using 3D PIC simulations. We geometrically optimize the target to increase the absorption of laser light and energy (temperature) and the number of hot electrons. To exp...

We report the possibility of a time-resolved bacterial live/dead dynamics observation with the use of plasmonic nanospikes. Sharp nanospikes, fabricated on a 500-nm thick gold film by laser ablation with the use of 1030-nm femtosecond pulses, were tested as potential elements for antibacterial surfaces and plasmonic luminescence sensors. Staphyloco...

A 50-nm-thick alloyed gold-palladium film on a silica substrate was dewetted by 1060-nm/ns laser pulses and characterized by scanning electron microscopy. Optical transmission spectroscopy of the millimeter-sized spot of the dewetted film demonstrates pronounced Fano resonances, typical for large regular arrays of oligomers of plasmonic nanoparticl...
Article
A natural diamond surface was nanopatterned in a subablative scanning mode by multiple tightly focused 515-nm, 300-fs laser pulses, resulting in regular surface metagratings (nanoripples) with a subwavelength period of Λ ∼ 100 nm, an almost undistorted crystalline structure, free from sp²-carbon, oriented perpendicular to the laser polarization, an...
Article
The transmission of near infrared femtosecond laser pulses (wavelength of 800 nm) and supercontinuum radiation (300–750 nm) generated by them through a 50-nm gold film immersed in water has been experimentally studied at the power of focused laser radiation in the range of 1–10 GW. An increase in the excitation intensity is accompanied by the blues...
Article
Low- and ultralow-energy tightly focused 200 fs, 515 nm donut-shaped laser pulses at 0.25 and 0.65 NA focusing were used for single-shot ablative pulse-energy scalable nanopatterning of 50 nm thick gold film and the following plasmonic excitation of dye monolayer photoluminescence (PL) in the fabricated nanostructures, respectively. The same pulses...
Article
Experimentally obtained nanostructures shaped as a through hole with a particle at the center are considered. Their electrodynamic parameters are studied using numerical simulation methods. It is shown that such structures function similarly to parabolic antennas.
Article
Experiments on initiating an electrical discharge with a developed streamer structure in atmospheric pressure air are described. The discharge was initiated in a quasi-optical linearly polarized microwave beam with a subcritical field. Air breakdown was initiated by an electromagnetic vibrator placed in free space, on the surface of a dielectric pl...

Large-scale surface nanopatterning of commercial silicon (Si) wafer in the form of regular 1D-arrays of high-aspect ratio vertical nanosheets for anti-fouling and other potential promising – optoelectronic, nanophotonic and sensing applications was performed via multi-shot picosecond IR-laser ablation under a 5-mm thick carbon disulfide liquid laye...
Article
Some specific features of the transport of silver nanoparticles onto a SiO2 substrate under focused nanosecond IR laser pulses is experimentally investigated. A possibility of obtaining silver coatings is demonstrated. The formation of silver nanostructures as a result of pulsed laser ablation in air is studied. Nanoparticles are formed by exposing...
Article
The results of experimental studies on using an electrical discharge with an extended streamer structure in a quasioptical microwave beam in the multipoint ignition of a propane–air mixture have been reported. The pulsed microwave discharge was initiated at the interior surface of a quartz tube that was filled with the mentioned flammable mixture a...
Article
The results of experiments on the electrical breakdown of air in a quasi-optical microwave beam with a deeply subcritical initial field have been reported. Breakdown has been initiated by a cylindrical vibrator with spherically rounded ends and a vibrator with a tapered end. The experimental data suggest that the amount of initial breakdown-initiat...
