  The effects of laser-plasma interactions (LPI) on the dynamics of inertial
confinement fusion hohlraums is investigated via a new approach that
self-consistently couples reduced LPI models into radiation-hydrodynamics
numerical codes. The interplay between hydrodynamics and LPI -- specifically
stimulated Raman scatter (SRS) and crossed-beam energy transfer (CBET) --
mostly occurs via momentum and energy deposition into Langmuir and ion acoustic
waves. This spatially redistributes energy coupling to the target, which
affects the background plasma conditions and thus modifies laser propagation.
This model shows reduced CBET, and significant laser energy depletion by
Langmuir waves, which reduce the discrepancy between modeling and data from
hohlraum experiments on wall x-ray emission and capsule implosion shape.
