Abstract

We describe our preliminary observations of the interaction of short pulse 1 µm radiation with crystalline silicon. In particular we find that for 7 ps pulses, but not for 46 ps pulses, the crystal-amorphous transition can be induced on the Si surface. Additionally, we have measured the single shot melting threshold for c-Si to be 0.6 ± 0.2 J cm-2 for 7 ps pulses. The formation of ripple patterns and other surface structures with pulses as short as 4 ps is also reported.
