Plasma created in focused beams of electromagnetic waves in the terahertz frequency
range is a fairly new object in gas discharge physics. The specified range, located between …

The possibility and prospects of extreme ultraviolet (UV) point-like source development are
discussed in the present paper. The UV source is based on the discharge sustained by …

Metastable states in an atomic energy-level structure greatly influence atomic processes in
plasmas. In particular, high-energy long-lived metastable levels brought about by 5 s and 4 f …

We characterize extreme ultraviolet (EUV) emission from mid-infrared (mid-IR) laser-
produced plasmas (LPPs) of the rare-earth element Gd. The energy conversion efficiency …

We demonstrate high conversion efficiency for extreme ultraviolet (EUV) emission at 6.5–6.7
nm from multiple laser beam-produced one-dimensional spherical plasmas. Multiply …

The unresolved transition arrays (UTAs) emitted from laser produced bismuth (Bi) plasma
sources show potential for single-shot live cell imaging. We have measured extreme …

We have systematically observed extreme ultraviolet (EUV) spectra from highly charged ions
of nine lanthanide elements with atomic numbers from 60–70 in optically thin plasmas …

We describe the production of mid-infrared (mid-IR) short carbon dioxide (CO 2) laser pulses
with variable durations from 3 to 15 ns at a maximum pulse energy of 150 mJ/pulse using a …

XUV spectra of ns-and ps-laser produced platinum (Pt) plasmas in the 1–7 nm wavelength
region, where Δn= 1 n= 4–5 and Δn= 0 n= 4-4 transitions dominate the observed emission …

Extreme ultraviolet (EUV) optical transitions of lanthanide highly charged ions have been
studied. The [Ni] 4 s 2 4 p–[Ni] 4 s 2 4 d and [Ni] 4 s 2 4 p–[Ni] 4 s 4 p 2 transition lines of …
