Abstract
General issues relevant to the probing of plasmas with backlighters are first discussed. It is shown that soft x-ray wavelengths (> 10 nm) can generally probe thicker plasmas than harder radiation (< 1 nm) if the plasma is hot (> 100 eV). Demonstration experiments are discussed where the transmission of x-ray lasers through other laser-heated solid targets have been used (i) to measure the rate of laser ablation of solid targets and (ii) to probe the opacity of a plasma material. It is shown that narrow bandwidth radiation, such as from an x-ray laser, offers the ability to probe much more optically thick plasmas than backlighters composed of moderate to wide bandwidth spectral lines.

The first Cepheid variable star was observed in York by John Goodricke. Their periodic oscillation frequency ∞ luminosity and so enables their use as ‘standard candles’ for the measurement of astronomical distance. However, the frequency of oscillation also depends on the plasma opacity.
