Laser Produced Plasma X-Ray Ultraviolet (XUV) Radiation Source

XUV radiation from a laser-produced plasma was investigated using a 1.5 m grazing incidence monochromator with a channel electron multiplier array detector. This instrument provides relatively high spectral resolution as well as linear response over a large dynamic range. Spectra from 8 to 40 nm were obtained from plasmas generated by a 0.5 J Nd:YAG laser focused on the following different target materials: Al, Cu, Fe, Sn, Sm, Hf, Yb, W, and Pb. Reproducibility of emission and effects of laser energy and focus on the output were measured.
