Wavelength Detuning for Cross-Beam Energy Transfer Mitigation in Polar-Direct-Drive Ignition

Polar direct drive (PDD) allows for direct-drive–ignition experiments at the National Ignition Facility (NIF) while the facility is configured for x-ray drive. For the first time, a PDD target design has been developed for ignition that includes the physical effects of cross-beam energy transfer (CBET) and nonlocal heat transport, both of which substantially alter the target drive.

Here, the ignition design is shown near the time of peak convergence.
