LLNL researchers developed a driver design for IFE-class lasers that allow for simultaneous high energy and high repetition rate operations.  The LLNL invention integrates an amplifier head featuring a mosaic architecture with a modified high power diode delivery system that is designed to achieve uniform and geometry-match illumination of the mosaic structured amplifier module. 

Powder atomic layer deposition process is used to coat nanopowders of host materials (e.g. yttrium aluminum garnet) with optically active neodymium organometal precursor followed by O₂/O₃ RF plasma to convert to a single layer of Nd₂O₃. The process can be repeated to build arbitrarily thick layers with custom doping profiles and followed by post-…
