FIG. 1.

Interferometric fringe pattern (a) and reconstructed density profile (b) of an unperturbed gas jet flow. The 3 TW beam propagates from left to right along x-direction.

Experimental setup.

FIG. 3.

Schlieren images of the shock front (a) and the corresponding SPARC simulations (b) of the shock wave propagating through an downward flow for different delays. The velocity of the gas is calculated by tracking the position of the tangential point “P.” Brighter colors in (b) correspond to a higher gas density.

Image of FIG. 4.
FIG. 4.

The vertical and the horizontal positions of the shock front [point “P” from Fig. 3(a)] as a function of time. A linear fit is applied to the vertical data to extract the vertical velocity component of the gas expanding into the vacuum. A polynomial fit is used for the horizontal data.
