A monoenergetic gamma-ray (MEGa-ray) source based on Compton scattering, targeting nuclear physics applications such as nuclear resonance fluorescence, has been constructed and commissioned at Lawrence Livermore National Laboratory. In this paper, th

Phased arrays remain an important strategy for scaling average power and pulse energy in optical fiber lasers. In zero-order arrays, the lengths of the constituent lasers or amplifiers are matched to within the coherence length of a pulse; for fibers

The authors report on a single-mode optical fiber that transmits one and only one polarization state of the fundamental mode over a broad wavelength band (13%). The good broadband performance is attributed to the fiber's refractive-index profile, whi

Recently continuous wave fiber laser systems with output powers in excess of 500W with good beam quality have been demonstrated [1]. High energy, ultrafast, chirped pulsed fiber laser systems have achieved record output energies of 1mJ [2]. However,

We have investigated fiber-based lasers that mode-lock via three nonlinear mechanisms: pulse evolution, bend loss, and tunneling. Experiments with nonlinear pulse evolution proved especially promising; we report here a fiber laser that produces 25 nJ

Single-mode, single polarization (SP), optical fibers of the W-tunneling type have been previously reported.1 Unfortunately, the width of the SP band has been small, 5%, making mass production uneconomical. We report a similar fiber with a much large

We prepared optical thin films of several fluoride materials using ion-assisted deposition. The materials were selected for their transmittance in the near ultraviolet and include LaF3, CeF3, NdF3, and cryolite. We investigated the effects of the ion

The practical problems of using ion-assisted deposition with substrate rotation are discussed, including the role of ion energy vs total ion flux. We compare MgF2, ZrO2, and SiO2 films made conventionally and with intermittent ion bombardment in term

Aluminum oxide films have been deposited by ion-assisted deposition. The films were electron beam evaporated at a chamber temperature of 100°C with argon and/or oxygen ion bombardment. The optical constants of these films have been measured in the v
