X-UV gain amplification studies in laser plasma using normal incidence multilayers mirrors
Abstract
Experiments were carried out in order to measure the amplification of spontaneous emission (ASE) of XUV radiation in a laser plasma. The experimental setup consisted of a multilayer mirror, an Optical Multichannel Analyzer detector, and a scintillator. The normal incidence reflectivity of the multilayer mirror was measured in the 100 A range. The contribution of incidence reflectivity to the shape of the recorded laser spectra is described within the framework of a theoretical model which takes into account effects of the imperfections between successive layers. The effect of single pass amplification enhancement on the absorption coefficient of the laser plasma is discussed.
