Abstract
We reported an all-fiber gain-switched mode-locked thulium-doped fiber laser operating at 1925 nm. A 1570 nm mode-locked laser with pulse width and repetition rate of 340 ps and 6.54 MHz, respectively, was used as a pump source. We generated gain-switched pulses with a maximum frequency of 25.8 kHz at 126 mW pump power. Mode-locked pulses were simultaneously generated and were visible inside the gain-switched envelope. The pulse width, repetition rate, average power, and peak power of the mode-locked pulses at 1925 nm were 105 ps, 20 MHz, 4.9 mW and 2 W, respectively, at a pump power of 160 mW.

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
