Abstract
A 250-microm-bore size and 50-cm-length hollow-glass waveguide (HGW) coated with a thin film of silver has been used to transport laser pulses at 800 nm from a Ti:sapphire oscillator. The silver film is deposited by a liquid-phase process. The measured transmission of this silver-coated HGW is 95%, which is considerably higher than the transmission of HGWs with no coating, as reported by other groups. The image of the output beam taken at different distances from the fiber output shows that a single HE11 mode couples to free-space modes from the exit of the fiber. Considerable spectral broadening can be obtained with high-intensity femtosecond pulse when this waveguide is filled with argon. This HGW can be used for such applications as beam transport and optical-pulse compression.

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
