Paper Abstract

Planar nanosecond shock waves were generated with ultrafast Gaussian laser pulses by using saturable dye-doped polymer film as shock layer. Ultrafast spatially resolved Coherent Anti-Stokes Raman (CARS) spectra of shock compression of a polycrystalline anthracene optical gauge were measured, and temporal profile and velocity of the shock pulse were obtained. Detailed measurements showed the shock pressure, as indicated by the blueshift of an anthracene vibrational transition, and the shock velocity, as indicated by the arrival time of shock wave at the anthracene gauge layer, remains constant within better than 5% over the central region probed by CARS.
