Analysis of images of the full solar disk obtained by ground-based (BST-2, CrAO RAS) and space-based (SDO/AIA, SDO/HMI) instruments and the potential approximation method revealed some features of the evolution of a long-lived coronal hole (CH) of 20

Based on the developed method of jointly using data on the magnetic fields and brightness of fila- ments and coronal holes (CHs) at various heights in the solar atmosphere as well as on the velocities in the photosphere, we have obtained the followin

The relationship between two classes of coronal holes and high-speed quasi-stationary streams of solar wind at the Earth’s orbit is investigated. “Open” coronal holes, whose area is invariable or increases with the height over the solar surface

The gain spectrum of a long-pulse ( ~ 0.5 μs) XeCl laser was investigated in a master oscillator—single-pass amplifier configuration. One Fabry—Perot etalon with a free spectral range ~200 cm-1 and a finesse F = 30 was used to tune the frequency

A long-pulse XeCl laser has been developed which is capable of generating, under conditions of active mode locking, trains of ultrashort pulses 100 ps long which are continuously tunable over the interval 307.6–308.6 nm. The number of pulses in a t
