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…

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…

LLNL has a patented process to produce colloidal silica directly from geothermal fluids. Livermore’s process uses membranes to produce a mono-dispense slurry of colloidal silica particles for which there are several applications. LLNL has demonstrated that colloidal silica solutions that result from extraction of silica from geothermal fluids undergo a transition to a solid gel over a range of…
