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…

LLNL’s novel approach utilizes a number of techniques to improve reconstruction accuracy:
- Better coding scheme-based techniques
- Hardware-assisted techniques
- Adaptive fringe projection techniques
- Multi-exposure based techniques
The method requires specific calibration procedures and control of the hardware, which is achieved through a digital twin…

Versatile Cold Spray (VCS) enables deposition of brittle materials, such as thermoelectrics, magnets, and insulators, while retaining their functional properties. Materials can be deposited on substrates or arbitrary shapes with no requirement to match compositions. The VCS system is low cost, easily portable, and easy to use.
VCS has been developed in a collaboration between Lawrence Livermore…
