Buried Depressed-Cladding Waveguides Fabricated in RE<sup>3+</sup>:CLNGG Laser Crystals using Direct Laser Writing Technique
Bibliographic record
Abstract
For at least a decade now, direct writing with a femtosecond (fs) laser beam technique (FS-DLW) is employed for waveguide fabrication in various transparent optical materials [1]. This method makes use of an fs-laser beam to induce changes of the material's optical properties, these modifications being dependent on the medium's nature, on the fs-laser beam parameters, as well as on the focusing conditions [2]. For crystalline and ceramic materials, waveguiding is commonly realized in the volume confined between the written tracks (Type II waveguides), with double-wall or more complex structures. Among YAG and YVO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</inf> crystals, laser gain media with partially disordered crystalline structure have been of great interest because they possess a unique combination of spectral and thermal properties [3–5]. They are a good candidate for generation of short and ultra-short laser pulses from compact structures, using passive Q-switch regime or mode-locking technique.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
