Evolution of MOPA beamline designs for laser fusion research (Invited Paper)
28 January 2025 • 8:30 AM - 9:00 AM PST | Moscone South, Room 76 (Lower Mezz)
Abstract
The architecture and technology of the master oscillator power amplifier (MOPA) that comprise a beamline of the multi-beam fusion lasers such as NIF that have recently demonstrated fusion scientific gain greater than one, that have evolved over the more than 50 years of research in Inertial Confinement fusion (ICF). The majority of ICF lasers worldwide such as NIF, the Omega laser at the University of Rochester, Laser Megajoule in France and SGIII in China are frequency tripled Nd doped phosphate glass systems. This presentation will summarize the advances that have been made in propagation including non-linear effects, multi-pass architectures and precision pulse shaping that has led to the recent achievement on NIF. While the focus of the presentation will be solid state lasers, the architecture and system strategies for excimer lasers that are also viable candidates for future IFE systems will also be discussed.
