Abstract:An imaging-velocity interferometer system for any reflector (VISAR) has been implemented at the “Heaven-I” excimer laser system, which is applied to laser-driven shock experiments as a method for equation of state (EOS) measurement. It contains three parts: input system, imaging relay system and interferometer system, and a single longitudinal mode laser with 532 nm wavelength is used as the probe light. The imaging VISAR performs at spatial resolutions better than 10 μm. In the experiment with a single-step aluminium target, the shock velocity and the free surface velocity could be measured simultaneously.
Keywords:velocity interferometer system for any reflector  spatial resolution  single-step target  shockwave
