Abstract
A high-power compact continuous-wave (CW) Nd:YAG laser with greatly improved beam quality operating at 946 nm is reported. A simple concave-plane cavity was made with a composite Nd:YAG laser crystal which was pumped by a fiber-coupled laser diode. A maximum output power of 9.63 W was obtained at an incident pump power of 31 W with beam quality factor M2 ~ 5. To the best of our knowledge, this is the highest output power at 946 nm with such a beam quality that was produced from diode-pumped Nd:YAG lasers using bulk crystals.

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
