Laser Drivers

AbstractHigh-power laser drivers are located in huge laser facilities built for inertial confinement fusion, and have achieved important progresses in the past decade; however, many unconventional optical elements implemented still cannot be accurately measured. To solve this problem, the ptychographic iterative engine (PIE), which is a recently developed technique that can detect both the phase and modulus of the light field simultaneously, is adopted to measure the transmission function of these optical elements and then to accurately characterize their key parameters. The distinctive advantage of PIE over other traditional metrology techniques in measuring large optical elements is demonstrated in this paper by detecting the focal length of a lens array and the surface profile of a continuous phase plate.

The Relationship

AbstractThe targets used in inertial confinement fusion (ICF) experiments at the Lawrence Livermore National Laboratory are plastic capsules roughly 0.5 mm in diameter. This paper reviews the fabrication of these capsules, focusing on the production of the thinwalled polystyrene microshell mandrel around which the capsule is built. The relationship between the capsule characteristics, especially surface finish, and capsule performance is discussed, as are the methods of surface characterization and modification necessary for experiments designed to study the effects of surface roughness on implosion dynamics. Targets for the next generation of ICF facilities using more powerful laser drivers will have to be larger while meeting the same or even more stringent symmetry and surface finish requirements. Some of the technologies for meeting these needs are discussed briefly.

Thickness Measurements

Thickness measurements of thin films are performed by both energy-dispersive x-ray spectroscopy (EDS) and x-ray fluorescence (XRF). XRF can measure thicker films than EDS, and XRF measurements also have somewhat greater precision than EDS measurements. However, small components with curved or irregular shapes that are used for various applications in the the Inertial Confinement Fusion program at LLNL present geometrical problems that are not conducive to XRF analyses but may have only a minimal effect on EDS analyses. This work describes the development of an EDS technique to measure the thickness of electroless nickel deposits on gold substrates. Although elaborate correction techniques have been developed for thin-film measurements by x-ray analysis, the thickness of electroless nickel films can be dependent on the plating bath used. Therefore, standard calibration curves were established by correlating EDS data with thickness measurements that were obtained by contact profilometry.
