Abstract

Abstract

Methods for facilitating the fast energy release of aluminum to enhance detonation performance will be discussed. The energy release rates of milligram-quantity samples have been compared by measuring the laser-induced shock wave velocities and tracking the formation of AlO on both the microsecond- and millisecond-timescales.

Abstract

Abstract

High-resolution optical optical diagnostics have long been used to characterize the expansion and electron density of dense laser plasmas. We describe recent studies of remotely-created dense laser plasmas produced by laser air-filaments that project high intensity laser light to distances of a kilometer.
