Abstract
We demonstrated a self-Q-switched mode-locked erbium-ytterbium co-doped fiber laser at 1570 nm. The repetition rate of Q-switched pulses increased from 3.25 kHz to 24.41 kHz, whereas pulse width reduced from 28.8 µs to 4.61 µs. Self-mode-locked pulses appeared inside Q-switched pulses just above the threshold and transitioned into mode-locked pulses beyond a pump power of 695 mW. The average output power, minimum pulse duration, and repetition rate of the mode-locked pulses were 160 mW, 340 ps, and 6.57 MHz, respectively, at a pump power of 2.4 W. Self Q-switched pulses were obtained at low pump power ranging from 205 mW to 694 mW. At high pump power, the Q-switched mode-locked pulses were switched entirely to a mode-locked regime. They stayed up to the maximum available pump power of 2.4 W. We presented the characteristics of the mode-locked laser and discussed their origin.

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
