Abstract The keV and XUV spectra of plasmas produced by the interaction of a laser pulse of various duration and wavelengths with, a solid Al target are compared and discussed. Drastic decrease of the XUV emission from the high ionization states was observed with the shortest pulses (500fs) and the shortest wavelength (0.5μm), which may be due to rapid cooling and quenching of ultrashort-lived and initially ultra-dense plasmas.
