Energy transport in plasmas produced by a high brightness KrF Raman laser
Optics Communications 89:5-6 (1992) 410-413
Abstract:
A high brightness KrF Raman laser generating 60 GW, 40 ps pre-pulse free pulses has been focused to an 8 μm focal spot at 9x1016W cm-2. Axial and lateral transport of energy has been studied by analysis of X-ray images of the focal spot and from X-ray spectra emitted by a thin layer of aluminium beneath a variable thickness of CH polymer on planar targets. The results show strong lateral transport of energy and reduced axial penetration of heating. © 1992.Calculations of the radiative opacity of laser-produced plasmas

Abstract:
We have observed laser oscillation on the B’2Δ-X2n (3-10) and (3-11) transitions of an F2 laser pumped nitric oxide laser. The maximum total output pulse energy was 280μJ. We present here the results of an investigation to determine the maximum intra-cavity loss which still allows laser oscillation to occur in this system. This information has been used to find the effective gain coefficient of the NO laser, operating on the B’2Δ-X2n (3-10) transition at 218 nm by applying the condition for cw laser oscillation. The effective cw gain coefficient was found to be 0.25 cm-1 for pump laser intensities of 20 MWcrrr2. © 1992 IOP Publishing Ltd.Improvements to ion-correlation experiments in dense plasmas
