Abstract
Abstract Structured light is extensively employed in optical measurements due to its exotic behaviors in light‐matter interactions. Notably, it exhibits exceptional capability in detecting the nonlinear response of optical media. Nevertheless, current detections enabled by structured light are limited to local nonlinearities. Here, an approach for measuring highly nonlocal nonlinear responses via a circular Airy beam is demonstrated. Under the action of a highly nonlocal nonlinearity, the profile of the beam is reshaped to a ring pattern whose size is linearly increased with the injected optical power. The slope of the linear relation reveals the nonlocal response, as proved by the theory. Experimentally, the method is verified by testing a typical medium having a highly nonlocal nonlinearity. The findings may trigger more studies on the measurement of optical nonlinearities via structured light.

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
