    "abstract": "Rich populations of clusters have been observed after femtosecond laser\nablation of bulk silicon in vacuum. Size and velocity distributions of the\nclusters as well as their charge states have been analyzed by reflectron\ntime-of-flight mass spectrometry. An efficient emission of both neutral silicon\nclusters Sin (up to n = 6) and their cations Sin+ (up to n = 10) has been\nobserved. The clusters are formed even at very low laser fluences, below\nablation threshold, and their relative yield increases with fluence. We show\nthe dependencies of the cluster yield as well as the expansion dynamics on both\nlaser wavelength and laser fluence. The mechanisms of the cluster formation are\ndiscussed.",
