Warm dense matter at the bench-top: Fs-laser-induced confined micro-explosion

Gamaly, Eugene G; Vailionis, Arthuras; Mizeikis, Vygantas; Yang, W; Rode, Andrei V; Juodkazis, Saulius


We report the experimental evidence for creation of Warm Dense Matter (WDM) in ultrafast laser-induced micro-explosion inside a sapphire (Al 2O 3) crystal. We show that the WDM can be formed by a 100nJ fs-pulse if the following conditions are satisfied: (1) the laser pulse is tightly focused to inside of the bulk of transparent material so the intensity at focus is two orders of magnitude higher than the optical breakdown threshold; (2) the pulse duration is shorter than the electron-ion energy...[Show more]
