Multi-atmospheric pressure, pulsed electric discharge excited lasers require pre-ionization to produce spatially uniform glows. Many such systems use corona bars to produce ultraviolet (UV) and vacuum ultraviolet (VUV) light as photo-ionization sources for this purpose. Corona bars are transient surface discharges, typically in a cylindrical geometry, that sustain high electron temperatures and...

Measurements of the phase two-photon matrix elements are presented for resonant and antiresonant two-color ionization helium. A tunable, narrow-bandwidth, near-infrared (NIR) laser source is used extreme ultra-violet (XUV) high-harmonic generation (HHG). The 15th harmonic within (1+1') XUV+NIR ionization, tuned in out resonance with members 1s$n$p $^1$P$_1$ ($n=3,4,5$) Rydberg series, covering ...

Recently, there has been a renewal of interest in the study of the effects of solar weather events on the ionization redistribution and irregularity generation. The observed changes at low and equatorial latitudes are rather complex and are noted to be a function of location, the time of the storm onset and its intensity, and various other characteristics of the geomagnetic storms triggered by ...
