Abstract

Second and third harmonic generation in the interaction of a prepulse-free 700-fs, 248-nm laser pulse with solid targets was observed for maximum intensities of ~5.10¹⁵ W/cm². Both s- and p-polarized light generated harmonic emission without observable difference. Harmonic generation was shown to prefer the specular direction. The results showed short-pulse ultraviolet lasers to be efficient drivers of harmonics in the vacuum ultraviolet (VUV) and extreme ultraviolet (XUV) range
