Paper Abstract

High-power, single longitudinal mode, single-polarization beam generates from a polarization maintaining double-clad Yb-doped silica fiber laser is more applicable for inertial confinement fusion (ICF) applications. The laser beamlets that converge on a target originate from a low power fiber laser in the master oscillator room (MOR). The laser seed signal amplifies through several cascaded amplifier chains in the front-end system. Today, the most famous fusion facilities, including National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL), Ligne d’Intégration Laser- Laser Mégajoule (LIL-LMJ) and OMEGA utilize fiber-based lasers. In this paper, we have compared various pumping modes comprising end-pumped master oscillator-power amplifier (MOPA) configuration and distributed sidepumped multifiber series fiber laser for scaling up the power of large-mode area (LMA) Yb:silica fiber laser for forward pumping regime.
