Cross-beam energy transfer saturation by ion trapping-induced detuning

Preliminary simulations for OMEGA relevant parameters reveal that pump depletion saturates CBET at densities above quarter critical Linear CBET theory predicts maximum energy transfer when the detuning frequency of the laser beams is equal to the Doppler-shifted frequency of the IAW The lower intensities and higher temperatures result in smaller amplitude IAWs, which reduces ion trapping and increases in the ion temperature Preliminary simulations for OMEGA relevant parameters reveal that pump depletion saturates CBET at densities above quarter critical
