Nonlinear propagation of localized wavefront deformation in high-power laser facility
Bibliographic record
Abstract
A theory model which describes the localized wavefront deformation of the optics elements is set up.The propagation regularity of the high-power plane-wave in the optics elements with localized wavefront deformation is investigated by linearization method of the ripple propagation.A continuous laser medium as an example is simulated with the model,and the spectral distribution clue to the localized wavefront deformation with different scales,the nonlinear gain of the amplitude clue to wave-front ripple with differen frequency,the relationship between the nonlinear gain and the beam transmission distance in the case of different B integral,the transmission distance where there exists the largest nonlinear gain of the output beam amplitude,and the amplitude distribution by the localized wavefront deformation are obtained.The simulation results show that to avoid damaging the optics it is nccessary to prevent the flaws from coming into being of 0.5~2.0 mm in radius on the surface of the optics.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
