Title: The influence of target irradiation conditions on the parameters of laser-produced plasma jets

Abstract

Recent experimental results demonstrate that the forming of plasma jets is a fundamental process accompanying the laser-produced plasma expansion, if a massive planar target with relatively high atomic number is irradiated by a defocused laser beam. In this paper some new results on the influence of target irradiation conditions on plasma jet parameters are presented. The experiment was carried out at the Prague Asterix Laser System (PALS) iodine laser [K. Jungwirth, A. Cejnarova, L. Juha, B. Kralikova, J. Krasa, E. Krousky, P. Krupickova, L. Laska, K. Masek, A. Prag, O. Renner, K. Rohlena, B. Rus, J. Skala, P. Straka, and J. Ullschmied, Phys. Plasmas 8, 2495 (2001)]. with the third harmonic beam of the pulse duration of 250 ps. The beam energies varied in the range of 13-160 J. The planar massive targets used in the experiment were made of copper. For measurements of the electron density evolution a three frame interferometric system was employed. The jets were produced in the whole range of the laser energy used. Calculations of the efficiency of the plasma jet production show that it decreases with increasing the laser energy.

  • The influence of focus spot and target thickness on multi-keV x-ray sources generated by 2 ns duration laser heated solid targets are investigated on the Shenguang II laser facility. In the case of thick-foil targets, the experimental data and theoretical analysis show that the emission volume of the x-ray sources is sensitive to the laser focus spot and proportional to the 3 power of the focus spot size. The steady x-ray flux is proportional to the 5/3 power of the focus spot size of the given laser beam in our experimental condition. In the case of thin-foil targets, experimental datamore » show that there is an optimal foil thickness corresponding to the given laser parameters. With the given laser beam, the optimal thin-foil thickness is proportional to the -2/3 power of the focus spot size, and the optimal x-ray energy of thin foil is independent of focus spot size.« less
  • A laser experiment on a plasma jet formation and its multidimensional numerical analysis are presented. Under suitable conditions on the laser intensity, focal spot radius, and target atomic number a radiative jet could be launched from a simple planar target. The jet lasts more than 10 ns and extends over several millimeters. It has a velocity of around 500 km/s, a Mach number greater than 10, and a density above 10{sup 18} cm{sup -3}. It is concluded from the dimensional analysis of the experiment and from numerical simulations that the x-ray emission has a dominant effect on the jet formationmore » and collimation. The similarity criteria for scaling of the laser experiment to larger systems are verified. Using a relatively low-energy laser pulse, below 500 J, one can produce a laboratory jet that presents similarities with astrophysical objects such as protostellar jets.« less
  • An investigation was made of the charge, kinetic, and geometric parameters of the ion component of a laser plasma in the final stages of expansion when the radiation was focused into a conical recess in a lead target. The dependences of these parameters on the cone vertex angle were determined and a comparison was made with plane targets. The measurements were made by probe and mass spectrometer techniques. The results suggest that a narrow highly directional plasma jet with a high degree of ionization can be produced by optimizing the target shape and the radiation focusing conditions. A possible mechanismmore » of the influence of collision processes on the resultant plasma parameters is discussed.« less
  • The results of investigations are presented that are connected with a very simple method of plasma jet formation, which consists in irradiating a massive planar target made of material with relatively high atomic number by a partly defocused laser beam. This brief communication is aimed at investigations of interaction of axially symmetrical light (plastic-CH) plasma with heavy (copper) plasma. It demonstrates that a relatively thin plastic plasma envelope can compress the Cu plasma and control the Cu-jet formation.
  • The dependences of the observed maximum proton energy on laser fluence, and the type and thickness of the target material were studied. The maximum proton energy depended on the laser fluence rather than on the laser intensity for laser pulses with energies between 40 and 430 mJ and pulse durations between 55 and 400 fs. The maximum proton energy increased as the product of target thickness and target mass density decreased. When a polyimide tape target of 7.5 {mu}m thickness was irradiated, the observed maximum proton energy and flux, counted as the number of etched tracks with a solid anglemore » of 0.25 sr, were 3.3{+-}0.1 MeV and 4x10{sup 6}/MeV/shot, respectively. For efficient proton acceleration when a wide ion emission angle is acceptable, polyimide was suitable for the tape target because it contains much hydrogen, and furthermore, it has a low mass density and a high tensile strength.« less
