High Time-Resolved Hugoniot Measurement by the Inclined-Mirror Method using a Long-Pulsed Laser

We produced a long-pulsed dye laser with no Q-switch for the shock-wave measurement or time-resolved spectroscopy under shock compression of solids. The average output power of this laser was larger than 13 kW (effective pulse duration ; ∼50 μs). This laser has been used as a light source for the Hugoniot measurement of solids by the inclined-mirror method combined with a rotating-mirror type streak camera. It was confirmed that the time resolution of Hugoniot measurement increased to higher than 1 ns.
