Schematic of six-ring design for IL-13352
High Power Microstructured Optical Fiber Amplifier Design Mitigating Stability Limitations

This LLNL invention proposes a new microstructured large mode area fiber design that enhances the confinement of the core mode while strongly suppressing thermal or scattering mediated dynamic couplings with higher order modes thought to be responsible for generating undesirable Transverse Mode Instabilities. The design accomplishes higher order mode suppression and core mode confinement by…

3D MEA device prior to actuation. A) A completed device. B) Close-up image of a single cell culture well. The large dark metal features at the top and bottom of each cell culture well are ground electrodes, which are all electrically shorted to each other. C) Light micrograph of a single 3DMEA post-actuation. The hinge regions are plastically deformed and allow the probes to stand upright without additional supports.
A 3-dimensional in vitro flexible microelectrode array (MEA)

To replicate the physiology and functionality of tissues and organs, LLNL has developed an in vitro device that contains 3D MEAs made from flexible polymeric probes with multiple electrodes along the body of each probe. At the end of each probe body is a specially designed hinge that allows the probe to transition from lying flat to a more upright position when actuated and then…

Spectral Beam Combining Grating Optic

Livermore Lab's SBC grating optics benefit from the combination of the following key technologies:

  • LLNL proprietary optical coating designs utilizing >100 thin film layers – enables ultra-low-loss, ppm transmission levels through the coating, high diffraction efficiency, and large bandwidth.
  • LLNL proprietary dispersive surface relief structure…
