Intramolecular vibrational dynamics of ν1 mode in (CF3)2C=C=O molecule induced by resonant IR femtosecond radiation

EPJ Web of Conferences, 2017
Intramolecular dynamics of the vibrational levels (up to v = 5) of the ν1 mode in (CF3)2CCO molecule, induced via multiphoton selective excitation of this mode by resonant femtosecond IR radiation, was studied.

Exploring optoelectronic properties and mechanisms of layered ferroelectric K4Nb6O17 nanocrystalline films and nanolaminas

Scientific Reports, 2017
Two-dimensional layered K4Nb6O17 (KN) was easily formed as a secondary phase caused by the volatilization of alkali metal ions, when preparing ferroelectric K x Na1−x NbO3 based ceramics and films.

Tracing multiple scattering trajectories for deep optical imaging in scattering media

Nature Communications, 2023
Multiple light scattering hampers imaging objects in complex scattering media. Approaches used in real practices mainly aim to filter out multiple scattering obscuring the ballistic waves that travel straight through the scattering medium.

Frequency stabilization of diode laser on the wavelength of 5P3/2→5D5/2 of rubidium transition

EPJ Web of Conferences, 2017
The method of frequency stabilization of diode laser on the wavelength of 5P3/2→5D5/2 of rubidium (776 nm) has been realized. The two-photon absorption spectroscopy of the rubidium vapors is underlie of the suggested scheme.

Nanolocalized UV source of laser radiation

EPJ Web of Conferences, 2017
We show the results of optical nonlinear interaction of laser light with plasmonic nanostructures. Creation of a nanolocalized source of UV radiation (λ = 260 nm) of the record high intensity was demonstated.

s2ISM: A Comprehensive Approach for Uncompromised Super-Resolution and Optical Sectioning in Image Scanning Microscopy [PDF]

EPJ Web of Conferences
Image Scanning Microscopy (ISM) enables good signal-to-noise ratio (SNR), super-resolution and high information content imaging by leveraging array detection in a laser-scanning architecture. However, the SNR is still limited by the size of the detector,

Variance Spectroscopy

The Journal of Physical Chemistry Letters, 2015
Spectroscopic analysis and study of nanoparticle samples is often hampered by structural diversity that presents a complex superposition of spectral signatures. By probing the spectra of small volumes within dilute samples, we can expose statistical variations in composition to obtain information unavailable from bulk spectroscopy. This new approach is
