Comprehensive study of antireflection coatings for mid-infrared lasers
Bibliographic record
Abstract
A comprehensive study is done for optimizing antireflection coatings at mid-infrared wavelengths around 3.4 μm for applications in semiconductor lasers. Different materials are tested for single and double layer coatings. The coatings are characterized by comparing the change in the threshold currents before and after coating the lasers. The change in the differential slope efficiency was used to estimate the loss in the coatings. The lowest value achieved for a single layer coating was 5% using aluminum oxide while a minimum value of reflectivity of 7 × 10−4 was achieved with a double layer coating of zinc selenide and silicon dioxide. The coatings' quality was tested using scanning electron microscopy and tape test. The study provides a comprehensive list of materials that can be used for antireflection coating applications in the mid-infrared region.

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.
