TL;DR: A series of experiments focused on high neutron yield has been performed with the Gekko-XII green laser system [Nucl. Fusion 27, 19 (1987)]. Deuterium-tritium (DT) neutron yield of 1013 and pellet gain of 0.2% have been achieved as mentioned in this paper.

TL;DR: In this paper, an absorption spectrum of a uniform Sn plasma generated by thermal x rays has been measured in the EUV range (9-19 nm wavelength) for the first time, showing that control of the optical depth of the laser-produced Sn plasma is essential for obtaining high conversion to 13.5 nm-wavelength EUV radiation; 1.8% of the conversion efficiency was attained with the use of 2.2 ns laser pulses.

TL;DR: Experimental results indicate that control of the optical depth of the laser-produced tin (Sn) plasma is essential for obtaining high conversion to 13.5 nm-wavelength EUV radiation.

TL;DR: In this paper, the authors proposed a two-pulse irradiation scheme for high CE, and reduced ion debris using a carbon dioxide laser and a droplet or a punch-out target.

TL;DR: In this article, the active medium for high-power and high-energy laser systems for laser-fusion research was evaluated and the performance of rod amplifiers and disk amplifiers was investigated.
