Laser matter interaction in the bulk of transparent dielectrics: Confined micro-explosion

Gamaly, Eugene G; Luther-Davies, Barry; Rode, Andrei V; Juodkazis, Saulius; Misawa, Hiroaki; Hallo, Ludovic; Nicolai, Philippe; Tikhonchuk, Vladimir T


We present here the experimental and theoretical studies of drastic transformations induced by a single powerful femtosecond laser pulse tightly focused inside a transparent dielectric, that lead to void formation in the bulk. We show that the laser pulse energy absorbed within a volume of less than 1μm3 creates the conditions with pressure and temperature range comparable to that formed by an exploding nuclear bomb. At the laser intensity above 6 × 1012 W/cm2 the material within this volume is...[Show more]
