| 2 | Development of high damage threshold laser-machined apodizers and gain filters for laser applications显示文摘We have developed high damage threshold filters to modify the spatial profile of a high energy laser beam. The filters are formed by laser ablation of a transmissive window. The ablation sites constitute scattering centers which can be filtered in a subsequent spatial filter. By creating the filters in dielectric materials, we see an increased laser-induced damage threshold from previous filters created using ‘metal on glass' lithography. | Patrick Rambo Jens Schwarz Mark Kimmel John L.Porter | 2016 | High Power Laser Science and Engineering2016，4，3： | 1 |
| 3 | Recent laser upgrades at Sandia's Z-backlighter facility in order to accommodate new requirements for magnetized liner inertial fusion on the Z-machine显示文摘The Z-backlighter laser facility primarily consists of two high energy, high-power laser systems. Z-Beamlet laser(ZBL)(Rambo et al., Appl. Opt. 44, 2421(2005)) is a multi-kJ-class, nanosecond laser operating at 1054 nm which is frequency doubled to 527 nm in order to provide x-ray backlighting of high energy density events on the Z-machine. Z-Petawatt(ZPW)(Schwarz et al., J. Phys.: Conf. Ser. 112, 032020(2008)) is a petawatt-class system operating at 1054 nm delivering up to 500 J in 500 fs for backlighting and various short-pulse laser experiments(see also Figure 10 for a facility overview). With the development of the magnetized liner inertial fusion(MagLIF) concept on the Z-machine, the primary backlighting missions of ZBL and ZPW have been adjusted accordingly. As a result, we have focused our recent efforts on increasing the output energy of ZBL from 2 to 4 kJ at 527 nm by modifying the fiber front end to now include extra bandwidth(for stimulated Brillouin scattering suppression). The MagLIF concept requires a well-defined/behaved beam for interaction with the pressurized fuel. Hence we have made great efforts to implement an adaptive optics system on ZBL and have explored the use of phase plates. We are also exploring concepts to use ZPW as a backlighter for ZBL driven MagLIF experiments. Alternatively, ZPW could be used as an additional fusion fuel pre-heater or as a temporally flexible high energy pre-pulse. All of these concepts require the ability to operate the ZPW in a nanosecond long-pulse mode, in which the beam can co-propagate with ZBL. Some of the proposed modifications are complete and most of them are well on their way. | Jens Schwarz Patrick Rambo Darrell Armstrong Marius Schollmeier Ian Smith Jonathan Shores Matthias Geissel Mark Kimmel John Porter | 2016 | High Power Laser Science and Engineering2016，4，4： | 0 |
