Theoretical Analysis of Efficient X-ray Lasers
Abstract
In this paper we outline theoretical development related to the concept of downsized ("small-scale", "table-top" ) X-ray lasers. The present status and the main characteristics of collisional table-top X-ray lasers of next generation will be described. We will cover two novel schemes of downsized X-ray lasers recently demonstrated in capillary Z-pinch discharges and laser produced plasmas. One of them is based on a fast electrical discharge in capillaries, which has been proven to be an effective and simple realization of soft X-ray lasers.(J.J.Rocca, V.N.Shlyaptsev, F.G.Tomasel et al,) Phys.Rev.Lett.,73,2192 (1994) The second represents a combination of a "classical" nanosecond laser pulse for plasma formation with powerful picosecond laser excitation to take advantage of a new method of population inversion, transient inversion, that has a duration of the order of the atomic lifetimes.footnote P.V.Nickles, V.N.Shlyaptsev, M.P.Kalashnikov, et al, Subm. to Phys.Rev.Lett. The results of comprehensive modeling of the kinetics, gas-dynamics and radiation transport of X-ray lasers will be presented. Work partially supported by NSF.
