Overview of main amplifier power conditioning for the laser fusion

This paper describes the novel power conditioning systems (PCS) with a pre-ionization/lamp check (PILC) for flashlamp-pumped laser. Its architecture is different from any traditional laser power conditioning system and was chosen as the most cost-effective way to reliably deliver the large amounts of electrical energy needed for laser ICF facilities. The design of the power conditioning systems represents an evolution that has occurred over many years and several generations of lasers. The direction of this evolution has been to build modules that can handle larger amounts of energy with a smaller number of components. Although the novel power conditioning design involves several technical challenges (The operation of parallel flashlamp, large module size, parallel capacitor, large capacity output switch), the PCS must also meet lifetime, reliability, and maintainability requirements that are derived from the operational requirements for the large laser system. The paper also describes the sensitivity of system performance of various fault-mode.
