Abstract
A tunable random feedback fiber laser with low intensity noise is proposed and experimentally demonstrated. The random feedback is effectively achieved by multiple reflections from 100 randomly spaced refractive index modulation regions over 10 cm SMF in both longitudinal and transverse directions. A tunable erbium-doped fiber ring laser with narrow linewidth of 2.4 kHz and a high side-mode suppression ratio of 59 dB is achieved over a 0.5 nm tuning range. The proposed fiber laser exhibits low relative intensity noise (<-120 dB/Hz) and low frequency fluctuation of ∼3.41×10(-11) over 5 s.

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
