Times Cited Count：0 Percentile：0(Optics)It is challenging to clearly distinguish the impacts of the optical field and collisional ionization in the evolution of the charge state of a plasma produced when matter interacts with high-intensity laser pulses. In this work, time-dependent calculations of plasma kinetics are used to show that it is possible only when low-density gaseous targets with sufficiently small clusters are used. In the case of Ar plasma, the upper limit of the cluster radius was estimated to be

Times Cited Count：8 Percentile：49.58(Nuclear Science & Technology)The experimental program on the JFT-2M tokamak started with the first plasma on April 27, 1983 and was completed in March, 2004. In the series of experiments for 21 years, a lot of significant results leading the fusion energy research and plasma physics have been produced. As the first paper of this special issue on all aspect of JFT-2M, this paper reviews the JFT-2M program.

Times Cited Count：16 Percentile：57.84(Optics)We have observed strong amplification for the 4d-4p transition of the Ni-like La ions at a wavelength of 8.8nm pumped by a chirped pulse amplificatio Nd:glass laser with an energy of 18 J. In this experiment, laser pulses consist of a pre-pulse and a main pulse with duration of 200ps and 7 ps separated by 250ps. The KeV X-ray spectroscopy and theoretical calculation indicate that the plasma temperature increasesd effectively by reducing the prepulse intensity, and that the substantial gain is generated in a small overcritical region heated by the electron heat transport.

The J-KAREN-P laser at the Kansai Photon Science Institute was irradiated to a cluster target and confirmed the second harmonic generation. Polarization measurements of the generated second harmonic revealed that the polarization plane of the component that passed through the laser-generated plasma was rotated. This result suggests that a vortex-like magnetic field centered on the laser axis is generated.
