Title Blast-wave diagnosis of self-focusing of an intense laser pulse
Abstract Self-focusing of intense laser pulses in a gas of atomic clusters is diagnosed in both long (700 fs) and short (100 fs) pulse regimes. This investigation uses blast-wave analysis techniques, which are sensitive to deposited energy, as a tool to identify locations of self-focusing. The detection of highly energetic x rays from the interaction of the short pulse with the clusters suggests the activation of electron acceleration in the self-focused high-intensity channels produced. The self-focusing is attributed to the optical properties of the clusters since it occurs at moderate laser powers and the cluster parameters are critical to the extent of the channel that forms.
