FIG. 3.

Heating by pump waves of amplitudes (solid black lines), (red dotted), (green dashed), (blue dot-dashed). Plasma frequency ; initial temperature of 5 eV, . Top: resonance frequency (thick lines), Landau damping rate (thin lines). Bottom: normalized thermal chirp rate . Left: (front of pump has traversed the plasma); right: .

FIG. 4.

As Fig. 3, but plasma frequency .

Image of FIG. 5.
FIG. 5.

Top: transverse (thin) and longitudinal (thick lines) plasma temperatures. Bottom: resonance frequency (thick) and Landau damping rate (thin). Solid lines: heating by the pump wave alone ; dashed lines: combined heating by pump, probe , and plasma waves. Left: (front of pump has traversed the plasma); right: . Bottom right (thin blue dot-dashed line): plasma wave amplitude. .

FIG. 6.

Snapshots of probe (thick black lines) and plasma wave (thin red lines) amplitudes (progressing from left to right). Top: monochromatic pump. Bottom: chirped pump set to compensate for the thermal chirp. (Note the different scales for probe and plasma wave.) , , and as in Fig. 5.

Image of FIG. 7.
FIG. 7.

Probe amplitude near the plasma slab exit for different pump chirp rates: (solid black), (dotted red), (dashed green), (long dashed blue), and (dot-dashed yellow). , , and as in Fig. 5.
