FIG. 1.

Comparison between 2D single-shot images of the LBMO plume emission in HV (left column) and at (right column), for three different delays after the laser pulse arrival on the target. Each image is obtained from a different laser shot, and is normalized to its own maximum intensity. marks the position of the target surface.

FIG. 2.

Temporal sequences of the LBMO plume emission at for three oxygen background gas pressures of , , and 1.2 mbar (from left to right). The time on the right side of the snapshots corresponds to the delay (in microsecond) after the laser pulse. Each image is obtained from a different laser shot, and is normalized to its own maximum intensity. marks the position of the target surface. The target-substrate distance in these acquisitions was .

FIG. 3.

Position-time plots of the LBMO plume front for the three values of the oxygen background gas pressure investigated, at . The symbols are the experimental points, and the solid line represent the free-plume front dynamics ( with ).

Image of FIG. 4.
FIG. 4.

Overall plume emission intensity as a function of (a) the time delay and (b) the plume front position . The arrows on the top axis in panel (a) indicate the delay at which the plume front hits the substrate at the indicated pressure.

FIG. 5.

Position-time plots of the plume front of Fig. 3 plotted in log-log scales. Free-plume indicates the free expansion , while PBW refers to a PBW-like propagation . The dashed line marks the position of the substrate at .

Image of FIG. 6.
FIG. 6.

Time and space-resolved emission spectra of the LBMO plume at for the three different background gas pressures , , and (from bottom to top). The pressure (in mbar) is indicated on the left side of the snapshots. The delay (in microsecond) after the laser pulse is reported at the bottom of each column. The spectra are normalized to the same maximum intensity, and the number in the top-right corner in each image indicates a multiplying factor. marks the position of the target surface. The labels on the upper left spectrum show the assignment of the most intense emission features.

FIG. 7.

(a) Comparison between 2D single-shot images of the LBMO plume emission at , with the substrate at RT (left column) and at (right column), for various delays after the laser pulse arrival on the target. Each image is obtained from a different laser shot, and is normalized to its own maximum intensity. marks the position of the target surface. (b) Position-time plots of the plume front at , with the substrate at RT and at . The symbols are the experimental points, while the solid line shows the free-plume behavior during the initial stage of the plume front propagation.
