Abstract
In this article, recent research works of warm dense matter are introduced. In the warm dense matte
research, how to diagnose the condition is always discussed because there are several difficulties.
Recently, there are many probe experiments with various probes produced by high power lasers. For
example, the X-ray Thomson scattering is now strong tool for determining the electron temperature and
density simultaneously. Beside it there are other potential methods to measure the parameters of the
warm dense matter. They include the fast e-beam diffraction and photoelectron spectroscopy. Features
of each probe measurement are briefly mentioned and the relation between unknown physics in warm
dense matter and expected measured parameters from these new diagnostics are introduced.
