Laser-produced plasma bubble

Laser-produced plasma bubble In the aftermath of a plasma in atmospheric density H 2 produced by a 6 ns, 600 mJ, 1064 nm, Nd:YAG laser pulse, a bubble develops behind the shock front. Within 2 μ s the shock detaches from it, but the bubble persists for 100 μ s before it is clearly turbulent. While initially spheroidal in appearance with a diameter of about 0.6 cm, after 16 μ s the enveloping cold gas penetrates the bubble along the axial channel left by the laser. This results in a distorted torus with a protrusion that moves slowly toward the laser. The images show that the gas processed by the laser-plasma shock front is isolated from the surrounding unprocessed gas until mixed by this flow. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review E American Physical Society (APS)

Abstract

In the aftermath of a plasma in atmospheric density H 2 produced by a 6 ns, 600 mJ, 1064 nm, Nd:YAG laser pulse, a bubble develops behind the shock front. Within 2 μ s the shock detaches from it, but the bubble persists for 100 μ s before it is clearly turbulent. While initially spheroidal in appearance with a diameter of about 0.6 cm, after 16 μ s the enveloping cold gas penetrates the bubble along the axial channel left by the laser. This results in a distorted torus with a protrusion that moves slowly toward the laser. The images show that the gas processed by the laser-plasma shock front is isolated from the surrounding unprocessed gas until mixed by this flow.
