Selective localised modifications of silicon crystal by ultrafast laser induced micro-explosion

Rapp, Ludovic; Haberl, Bianca; Bradby, Jodie E.; Gamaly, Eugene G.; Williams, Jim S.; Juodkasis, Saulius; Rode, Andrei V.


Femtosecond (fs) laser pulses focused and confined inside the bulk of a material can deposit a volume energy density up to several MJ/cm3 in a sub-micron volume. This creates highly non-equilibrium, hot, dense and short-lived plasmas with conditions favorable for arrangement of atoms into unusual material phases. Singlecrystal silicon was exposed to strong shock waves induced by laser micro-explosion in confined geometry. The conditions of confinement were realized by focusing 170-fs pulses,...[Show more]
