Sustained Acceleration of Over-dense Plasmas by Colliding Laser Pulses
We review recent PIC simulation results which show that double-sided irradiaton of a thin overdense plasma slab by ultra-intense laser pulses from both sides can lead to sustained comoving acceleration of surface electrons to energies much higher than the conventional ponderomotive limit. The acceleration stops only when the electrons drift transversely out of the laser beam. We show results of...
متن کاملXUV diagnostics of colliding laser-produced magnesium plasmas
Charge exchange collisions between highly charged Mg ions in colliding laserproduced magnesium plasmas are studied. Pinhole photography and XUV spectroscopy are used as diagnostic tools. XUV pinhole pictures taken at early stages give more insight into the expansion dynamics of the colliding magnesium plasmas. Spectroscopic studies show selective population of the n = 3 levels of Mg IX ions whi...
متن کاملEfficient acceleration of neutral atoms in laser produced plasmas
Recent advances in high-intensity laser-produced plasmas have demonstrated their potential as compact charge particle accelerators. Unlike conventional accelerators, transient quasi-static charge separation acceleration fields in laser produced plasmas are highly localized and orders of magnitude larger. Manipulating these ion accelerators, to covert the fast ions to neutral atoms with little c...

متن کاملMagnetic reconnection between colliding magnetized laser-produced plasma plumes.
Observations of magnetic reconnection between colliding plumes of magnetized laser-produced plasma are presented. Two counterpropagating plasma flows are created by irradiating oppositely placed plastic (CH) targets with 1.8-kJ, 2-ns laser beams on the Omega EP Laser System. The interaction region between the plumes is prefilled with a low-density background plasma and magnetized by an external...
