Autor: S. A. Filin, V. E. Rogalin, I. A. Kaplunov
Publikováno v: Journal of Applied Spectroscopy. 89:410-418
The possibility of controlling the chemical purity of the surface of optical elements by the ellipsometric method has been analyzed. The rationale of the possibility of measuring the parameters of contaminating films on the optical surface of element

Autor: Yu. V. Khomich, V. E. Rogalin, V. A. Yamshchikov, I. A. Kaplunov, T. V. Malinskiy
Publikováno v: Acta Astronautica. 194:434-441
Annotation In connection with the possible use of laser technological equipment in space the impact of nanosecond UV laser on copper and its alloys was investigated. At the pre-threshold mode, in the absence of obvious traces of melting, at an energy

Plastic Deformation of Copper and Its Alloys under the Action of Nanosecond UV Laser Pulse
Autor: T. V. Malinskii, V. E. Rogalin, V. A. Yamshchikov
Publikováno v: Physics of Metals and Metallography. 123:178-185
Abstract The effect of nanosecond UV laser pulses on copper and low-alloy copper samples has been studied. Traces of high-temperature deformation have been found at the energy density of 0.1–1 J/cm2 in the below-threshold regime without obvious tra

Heat Treatment of the Surface of the ChS57 Alloy with Powerful Nanosecond Ultraviolet Laser Pulses
Autor: S. I. Mikolutskiy, A. I. Ivanova, I. A. Kaplunov, V. E. Rogalin, Yu. V. Khomich
Publikováno v: Key Engineering Materials. 887:345-350
The threshold of optical breakdown of the nickel alloy ChS57 (Inconel) was measured at a wavelength of 0.355 μm with a laser pulse duration of 10 ns. Heat treatment of ChS57 above pulse energy density threshold (1 - 2.5 J/cm2) occurred mainly in the
