TL;DR: In this paper, the authors provide a comprehensive update of the current status of ultra-high-power lasers and demonstrate how the technology has developed, and what technologies are to be deployed to get to these new regimes, and some critical issues facing their development.

TL;DR: In this paper, the Ni-like Ag transient x-ray laser pumped under traveling wave irradiation was directly demonstrated for the first time, and the temporal history of the 13.9 nm laser pulse was measured with a high-resolution streak camera.

TL;DR: In this article, a high energy laser device that includes a gain medium comprising a solid material containing doping ions and having a first transverse dimension along a first axis (X), a second transverse dimensions along a second axis (Y), and a third axial dimension (e) along a third axis (Z), the three axes being mutually orthogonal, is described.

TL;DR: In this article, a laser de forte energie comprenant is presented, in which le milieu a gain presente un taux de dopage variable selon ledit troisieme axe de maniere a reduire l'amplification de l'emission spontanee, and des moyens de pompage delivrant un flux d'energie (Fp) au travers d'un plan defini par les premier and deuxieme axes.

TL;DR: In this paper, single pass gain of 77mm crystal and ceramic Yb:YAG disks were compared in the 100-200K temperature range on a laser amplifier cooled through a static low pressure helium gas cell.
