The initial experiments at NIF  were also designed based on this understanding which allowed optimization of laser intensity, wavelength and spot size, as well as target dimensions and materials, and further indicated the areas of greatest uncertainty where there was need for final empirical tuning. The recent studies at NIF have now confirmed for the first time that under ignition relevant conditions plasma instabilities produce self-generated optical scattering cells that are not only controllable but also useful. The experiments have further demonstrated that deleterious plasma scatter that depletes power from one set of beams can be compensated for by inducing a plasma scattering cell that redirects power from another set of beams. This has allowed induced plasma scattering to become the primary means to control the power deposition profile and the resulting implosion symmetry via adjustments to the laser wavelengths . These techniques have allowed enhanced target performance that is essential to the present experimental campaigns that study precision implosions , and were also an essential ingredient in the recent demonstration that net energy can be extracted from fusion fuel . This talk will review the plasma physics studied in the first few years of NIC experiments in the context of the earlier work and highlight its importance for fusion ignition with a laser.
