Abstract

fetched live from OpenAlex

A new method to enhance the output efficiency of the multi-frequency second harmonic generation process has been presented in the one-dimensional aperiodic optical superlattice by sandwiching linear layers between nonlinear media. The linear and nonlinear domain arrangements of aperiodic crystal are designed using the simulated annealing optimization method. The dependence of the output efficiency of second harmonic generation on the linear length has been investigated in detail; the most optimized structure being suggested. A comparison between pure nonlinear and linear‐nonlinear layered structures is presented which shows an increasing amount of the output efficiency in the presence of linear layers for the nonlinear aperiodic crystals.

Full frame distilled prediction

Teacher imitation

Not 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.
