Abstract
We report the generation of short-wavelength, high-order harmonics of intense laser radiation from atom clusters. Clusters containing about 10(3) atoms are produced in a high-pressure gas jet. We show them to b e a unique nonlinear medium. Compared with monomer gases they yield a higher appearance intensity for a given harmonic order, stronger nonli near dependence of harmonic signal on laser intensity, higher-order ha rmonics, and reduced saturation of the harmonic signal at high laser i ntensity.
