“…The mirror had near normal incidence reflectivity of 12% at 18.2 nm and in the second pass provided additional 120% increase in intensity (unfortunately some of pumping radiation was blocked causing decrease of the gain-length product). In transversely pumped SXL it was possible to place reflection mirror just at distance of ∼ 3 cm from lasing medium (high temperature plasma) for two-pass experiment [31]. Hence, with near normal incident reflectivity ∼ 20% of multilayer mirror intensity increase in the second pass exceeded by order of magnitude of the intensity in single pass [31].…”

Abstract:In this review we concentrate our attention on X-ray laser research and development covering the so called soft Xray region (down to ∼ 10 nm) and the "water window" region (down to 2.3 -4.4 nm). We present the development of soft X-ray lasers (SXLs) and their applications using primarily collisional and recombination schemes. We present the paths towards compact systems and major achievements to date. We discuss conditions for using both schemes to reach the "water window" region. In this discussion we also present another possible schemes based on photo-pumping, inner shell transitions in atoms and ions and "Doppler Compression" of IR laser radiation down to the X-ray region with its intrinsic tunability possibility. A significant part of the review is dedicated to the wide range of applications of SXLs with wavelengths at and above 10 nm. Also discussed is the potential of extending the range of biological applications for the "water window" region.Image of wafer with polysilicon lines on silicon (top: 250 nm, bottom: 100 nm widths of lines)

“…They were first used to amplify reflected soft xray stimulated emission in a second pass through the gain medium by Keane et al 47 A sophisticated demonstration of triple-pass amplification was reported by Ceglio et al 48 Encouraging progress has been made in fabricating mirrors for use around 44A in the difficult "water window" region. 49 Much of the high brightness and hence utility of conventional lasers arises from the optical cavity which enables the energy to be extracted in a low divergence beam.…”

The emerging technology of soft x-ray lasers is in a transition phase between the first laboratory demonstrations of gain and the acceptance of soft x-ray lasers as practical tools for novel applications. Current research is focussed on several fronts. The operational wavelength range has been extended to the "water window", important for applications in the life sciences. Gain has also been generated with substantially simpler technology (such as a 6J laser) and this augurs well for the commercial availability in the near future of soft x-ray lasers for a variety of applications. Advanced soft x-ray laser concepts are being developed from investigations into ultra-high intensity laser/matter interactions. The first applications of soft x-ray lasers to x-ray microscopy and holography have begun. In this paper a brief historical perspective of x-ray laser development will be followed by a review of recent advances in recombination, collisional and photo-pumped systems and applications. A summary of current gain-length performance achieved in laboratories worldwide is presented. Near term prospects for applications to novel fields are discussed.

“…During the four years since the Aussois Conference (1986), rapid progress has been observed in many areas notably in (i) the development of soft x-ray lasers (SXLs) at shorter wavelengths down to tb& "water window" (Matthews 1990, MacGowan 1990, (H) in the successful use of an SXL amplifier for the correction of refraction (Neely 1990), (iii) the first demonstration of a photopumped SXL (Boehly 1990), (iv) very elegant cavity experiments (Ceglio 1988), and (v) the first applications of SXLs to holography (Trebes 1987) and microscopy (DiCicco 1988). Very encouraging results in the development of small scale SXLs, have been reported (Kim 1989.…”
