Abstract
We report efficient cascade up-conversion generation due to two simultaneous quasi-synchronous processes of parametric decay ω3→ω1+ ω2 of pump quanta at the frequency ω3 and up-conversion of one of the generated waves ω1+ω3→ω4>ω3 at the frequency ω1 in a medium with a quadratic nonlinearity. It is found that the necessary condition for this generation is the requirement |γ1|2>(ω2/ω1)|γ1|2, where γ1,2 are the averaged constants of the nonlinear coupling for the processes ω1+ω2,3→ω3,4, respectively. If this requirement is fulfilled, the plane monochromatic pump wave is completely depleted, while the limiting (the noise seed intensity is I10,20→0 at the input) efficiency of the energy conversion into radiation at the frequency ω4 is independent of I10,20 and determined only by the relations between |γ1,2|2 and the frequencies of the interacting waves.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
