Evidence of a density grating under light induced formation of surface relief gratings at polymers containing azobenzene moieties
Bibliographic record
Abstract
The formation of a surface relief grating (SRG) on polymer films containing azobenzene moieties has been inspected during exposure with counter-rotating circularly polarized light of λwrite=488 nm by probing the diffracting efficiency of a second low power laser. In particular, the growing SRG was observed at films of different film thickness and with low and high light power of the writing laser. Using probe lasers of two different wavelength (λprobe=514 and 670 nm) the grating formation was inspected near the film surface and within the whole film, respectively. At low writing power (P=50 mW) and small film thickness (d<100 nm) only a SRG appears while at higher laser power and thicker films (d>300 nm) a density grating is also created within the film. The observations confirm the trends suggested by finite element calculations.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
