Optically pumped lasing from organic microcavity
Bibliographic record
Abstract
An optically pumped organic laser has been fabricated using a DCM (4-dicyanmethylene-2-methyl-6-4H-pyran)-doped Alq (tris (8-hydroxyquinoline) aluminum) film as the gain medium sandwiched between a high-reflectance distributed Bragg reflector and a silver reflector. The stimulated emission properties were investigated by short-pulse laser pumping. The intensity ratio of the resonant peak at 604 nm to the DBR (distributed Bragg reflector)-modulated free space emission band changed greatly with increasing pump energy density. The dependence on the pump energy density of the output properties including the cavity mode output, the total output, and the ratio of the cavity output versus total output, indicates a clear threshold energy density of 400 ± 20 µJ/cm 2 . The effective gain coefficient at the threshold was about 250 ± 14 cm 1 . PACS No.: 42.55.Sa

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.
