0.5-20 μm thin CsI:Tl scintillation screens with high spatial resolution were pre- pared by the thermal deposition method. It was proposed that the spatial resolution of the prepared conversion screens can be significantly improved by an additional substrate heating as well as by deposition of a carbon layer. Also thin CsI:Tl films deposited on mylar substrates can be used for non-destructive di ... More

Pump-probe experiment is widely used spectroscopic method. In case using different frequencies and different sources for pumping and probing there practically are no limitations on time duration of phenomena under investigation. But if using the same source for pumping and probing time range is limited by length of optical scheme from picoseconds to few nanoseconds. By using NovoFEL emission t ... More

Solid state chemistry studies several irreversible fast processes that require a single - bunch mode of investigation and are initiated by various external influences: detonation, shock waves, laser heating. As a result of this action, processes are initiated in the sample (adiabatic compression and heating, development of thermal stresses, increase of pressure in the local region), which creating ...

Laser nature of a continuous pulse-periodical radiation of the Novosibirsk terahertz free-electron laser appears in a good coherency of its pulses and very narrow synchronized longitudinal modes. Filtration of one of the modes by a system of three resonance Fabry-Perot interferometers allows to create laser source with monochromaticity which is sufficient for typical high-resolution THz spectrosco ...

Radially and axial polarized beams can be generated by superposition of orthogonally polarized Hermite-Gaussian-like beams which are equal in amplitude. The DOE which transforms Gaussian into Hermite-Gaussian modes was a plate with a phase step equal to half of the wavelength. The combination of the Hermite-Gaussian modes (1.0) and (0.1) gives us the Laguerre-Gaussian mode whose polarization stro ... More

Not fully ordered system (not crystals) are widespread in the surrounding nature, as well as in a number of new technologies. It seems natural to want to know what is inside, how different natural formations are arranged, or how accurately we created what we wanted. X-ray study can help us in this. As is known, X-ray structural analysis allows to reveal the internal structure of crystals up to th ... More
