X‐ray emission in the water window spectral region (2.3–4.4 nm) from materials (carbon, aluminum, titanium, copper, and molybdenum) irradiated by a 5 J/35 ns slab glass laser was recorded with a grazing‐incidence spectrometer for microscopy application. Carbon was determined to be the suitable source material for an x‐ray microscopy experiment. The absolute spectral brightness of the CVI 1s‐2p line and CV 1s2‐1s2p line emitted from the carbon plasmas was estimated to be ∼1.0×1016 photons/s/mm2/mrad2 in 0.1% bandwidth. The electron density and electron temperature of the carbon plasmas were derived from the x‐ray spectra and the conditions for intense emission are also discussed.
