Proposal for an extreme-ultraviolet selective autoionization laser in Zn III.
نویسندگان
چکیده
A system is proposed whereby Zn atoms that are photoionized by soft x rays from a laser-produced plasma undergo selective super-Coster-Kronig decay leading to inversion and lasing on several XUV Zn III transitions. Calculations indicate that lasing will occur when a moderate-sized (~10-J) 1.06-microm pump laser is used.

Observation of a Highly Excited Long-Lived Valence State in H2
We present the first observation of a long-lived valence state of H2 close to the ionization threshold, populated in a double resonance laser excitation scheme with extreme ultraviolet radiation in the first step. Level energies of rovibrational states, confined in the outer part of the double-well HHSg potential at a large internuclear distance of 11 a.u., have been determined with an accuracy...
متن کاملProbing and controlling autoionization dynamics of atoms with attosecond light pulses
The time evolution of an autoionizing atomic system is studied theoretically in the presence of a moderately intense dressing laser pulse. We first examine how an autoionizing wave packet evolves in time in the absence of an external field, and take the single 2pns(1P) resonances in beryllium as examples. Alternatively, we study the electron dynamics where an attosecond extreme ultraviolet (XUV...
متن کاملDirect identification of propargyl radical in combustion flames by vacuum ultraviolet photoionization mass spectrometry.
We have developed an effusive laser photodissociation radical source, aiming for the production of vibrationally relaxed radicals. Employing this radical source, we have measured the vacuum ultraviolet (VUV) photoionization efficiency (PIE) spectrum of the propargyl radical (C(3)H(3)) formed by the 193 nm excimer laser photodissociation of propargyl chloride in the energy range of 8.5-9.9 eV us...
متن کاملOpacity effect on extreme ultraviolet radiation from laser-produced tin plasmas.
Opacity effects on extreme ultraviolet (EUV) emission from laser-produced tin (Sn) plasma have been experimentally investigated. An absorption spectrum of a uniform Sn plasma generated by thermal x rays has been measured in the EUV range (9-19 nm wavelength) for the first time. Experimental results indicate that control of the optical depth of the laser-produced Sn plasma is essential for obtai...
متن کاملObservation of super Coster-Kronig-pumped gain in Zn III.
We report the observation of laser gain in the vacuum ultraviolet pumped by super Coster-Kronig decay. Using a 5-J, 300-psec pump pulse of 1064-nm radiation, we have observed gain on transitions in Zn III at 127.0, 130.6, and 131.9 nm with total gains of exp(2.4), exp(5.1), and exp(3.2), respectively. The large branching ratios of the rapid super Coster-Kronig decay into a small number of final...
