Probe signal as a function of gating beam delay using as the Kerr medium fused silica (circles) and NSF-66 (squares). The inset shows probe signal vs gating beam energy for the fused silica gate.
Gated measurement of a strong (7.5 ps) and a weak (0 ps) probe pulse. The dashed line indicates the background level caused by the strong pulse. The inset shows the weaker pulse measured with no strong pulse present .
Shadowgraphic images of a glass target irradiated at laser intensity at a probe delay of 2.5 ns (a) without and (b) with optical gating. The target has previously been subjected to 25 laser shots to enhance plasma self-emission.
Imaging of a wire through (a) zinc oxide wafer and (b) LBG glass. Structure in the glass prevents the use of this sample for an imaging application.
