摘要：

We present results of measurements of high-order harmonic generation and XUV spontaneous emission in helium and neon plasmas excited by a short pulse laser at intensities between 10(14) and 5 x 10(17)W/cm2. We compare the observed behavior of the harmonics with recent single atom calculations in helium. We observe a wavelength dependence to the efficiency of harmonic generation that has not been previously reported. We observe line emission from excited state transitions in Ne7+ for the first time in a short pulse laser-driven plasma. In particular, we see strong emission and a rapid recombination rate for the 9.8 nm (3d-2p) transition that is a possible candidate for a recombination-pumped X-ray laser.
