FIG. 5.

Decimal logarithm of the density of conduction electrons (in ) as a function of space and time.

Image of FIG. 6.
FIG. 6.

Evolution of the position of the absorbing front as a function of time (black curve). It is defined such that , thus leading to a significant absorption. The red curve is a fit of the latter curve with the function where is the fitting parameter whose optimized value is .

Evolution of the average velocity of the absorbing front as a function of the laser intensity.

Image of FIG. 8.
FIG. 8.

Transient images of two forming damage sites at two different delays at (a) −1.81 ns and (b) −1.27 ns illustrating the expansion of the modified region during the energy deposition phase. Image (c) shows the final (static) morphology of the damage sites. The image dimensions are .

Image of FIG. 9.
FIG. 9.

The parallel and cross-polarized components of a transient image captured at −1.73 ns delay illustrating the onset of the damage initiation in bulk KDP. The image dimensions are .

Image of FIG. 10.
FIG. 10.

Transient microscopic images () during laser damage initiation with a focused beam in the bulk of fused silica showing the parallel (I) and orthogonal (II) image components at delays (a) −2.20 ns, (b) −1.59 ns, and (c) 0.30 ns. The delays are measured between the peak intensities of the pump and probe pulses.
