Phase control of SBS PCM seeding by optical interference pattern clarified: Direct applicability for IFE laser driver

Abstract

Theoretical background of stimulated Brillouin scattering (SBS) seeded by a spatially localized optical interference pattern was investigated. Performed analysis revealed that the SBS may have its origin in the acoustic standing wave produced as a transient state between the initial optical interference field and the resulting stationary density modulation. Acquired knowledge can be found valuable in optimization of laser beam combination scheme considered e.g. for IFE applications. © 2010 IOP Publishing Ltd.
