Abstract
Abstract We report an ultra-low repetition rate self-started mode-locked fiber laser at 1.55 µ m spectral region with a sub-20 ps pulse duration at repetition rate of less than 100 kHz leading to high energy and peak power pulses. A repetition rate of 13.8 kHz with the pulsewidth of 17 ps is then achieved and the issue of multiple pulses is mitigated in the linear cavity structure by proper selection of semiconductor saturable absorber and dispersion management in the cavity. A broad supercontinuum achieved using 7 m SM-ZBLAN fiber while pumping with mode-locked fiber laser with repetition rate, pulsewidth, pulse energy and peak power of 53 kHz, 12.5 ps, 16.6 µ J and 1.3 MW, respectively.

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
