  • Synchronous excitation of multiple shock waves
    Patent number: 12148536
    Abstract: In some embodiments, a method to excite a shock wave in a target assembly includes: splitting a pulsed laser beam into a plurality of pulsed laser beams; spatially shaping the plurality of pulsed laser beams into a plurality of concentric pulsed laser rings of different diameters; and adjusting temporal and/or spatial intervals between the concentric pulsed laser rings to substantially match propagation times of a ring-shaped laser-driven shock wave from one ring to the next in a shock propagation layer of the target assembly.

  • Methods And Apparatuses For Enhancing Scintillation With Optical Nanostructures For Scintillators, LEDs, And Laser Sources
    Publication number: 20240210576
    Abstract: Methods and systems are disclosed that enhance the yield and speed of emission and control the spectral and angular emission of light emitted by materials under irradiation by high-energy particles through a process known as scintillation. In each case, a photonic structure (of nano- or micron-scale feature sizes) is integrated with a scintillating material, and the photonic structure enhances the yield or controls the spectrum of the material. Various embodiments of this technology and practical demonstrations are disclosed.
