Persistent full-vector 780 nm atom-coupling optimization

checkpointed currentartifacts updated 2026-09-05 14:21 UTC

The qualified 40 x 70 x 28 component-symmetry-reduced Maxwell solver is optimizing the centered z-dipole response at exactly 780 nm without a preset iteration count. Direct gates run every step; the independent 81-point, seven-probe Q diagnostic runs every tenth step and intervening checkpoints are provisional.

Decision. Continue while every-step direct gates pass. Run the full 81-point Q validation at iterations 10, 20, 30, and so on; label intervening retained checkpoints provisional. Pause for nonlinear mode reacquisition as soon as a physical target-window pole candidate appears.
