X-ray spectroscopy is a diagnostic tech・nique for laser-produced plasma in inertial confinement fusion research. Radiated spectra from high temperature plasma lead to information on the ionization state, the electron temperature and density. There are various methods in emission spectroscopy using continuum or line spectra. Absorption spectroscopy is applicable to low-temperature high-density plasma. Crystal spectrometers and filtered X-ray diodes are useful equipments for iaser-plasma X-ray spectroscopy. These techniques and instruments are briefly overviewed in this paper. In addition, one example of X-ray spectroscopic measurements for laser-produced plasma is reported. In this experiment, a micro-dot target was irradiated by KrF Iaser. Radiated X-ray from the plasma was observed by crystal spectrometers. The electron temperature was determined from free-bound continuum. The electron density was estimated from the intensity ratios of resonance line emissions and from the Stark broadened iine profile.
