AlGaN cladding-free 482 nm continuous wave nitride laser diodes grown by plasma-assisted molecular beam epitaxy
Bibliographic record
Abstract
The authors demonstrate continuous wave (CW) operating at 482 nm AlGaN-cladding-free laser diodes (LDs) grown by plasma assisted molecular beam epitaxy (PAMBE). The maximum CW output power was 220 mW. The PAMBE LD structures were grown on (0001) GaN substrates obtained by hydride vapor phase epitaxy, with threading dislocation density of 5 × 107 cm−2. The PAMBE process was carried out in metal-rich conditions supplying high nitrogen flux (ΦN) of 2 μm/h during quantum wells (QWs) growth. The authors found that high ΦN improves quality of high In content InGaN QWs. The role of nitrogen in growth of InGaN on wurtzite (0001) GaN surface as well as influence of LD design on threshold current density is discussed.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
