Pressure effect in a shock-wave-plasma interaction induced by a focused laser pulse
The effect of ambient pressure on the interaction between a laser plasma bubble and a shock wave involving a Richtmyer-Meshkov instability was experimentally studied via framing Schlieren visualization. A sharp plasma interface could be formed without any separation material that causes undesired di...

| description | The effect of ambient pressure on the interaction between a laser plasma bubble and a shock wave involving a Richtmyer-Meshkov instability was experimentally studied via framing Schlieren visualization. A sharp plasma interface could be formed without any separation material that causes undesired disturbances. The fundamental vortex structure which was produced via baroclinic effects was self-similar with respect to the laser energy-ambient pressure ratio. Yet, the higher the ambient pressure, the more high-wave-number instabilities were enhanced so as to contaminate the self-similarity. |
