Broadband terahertz radiation produced in an AgGaSe2 crystal
Bibliographic record
Abstract
The linear and nonlinear optical properties are investigated in a <110>-cut, 485 μm-thick AgGaSe<sub>2</sub> crystal. The linear optical properties are studied by performing terahertz time-domain spectroscopy measurements, which allow the refractive indices and the extinction coefficients to be calculated for the uniaxial AgGaSe<sub>2</sub> crystal. Optical rectification measurements are conducted to investigate the crystal’s nonlinear optical properties, which produce broadband terahertz radiation pulses having spectral components between 0.02 and 4 THz. Due to the large optical rectification coherence length exhibited by the AgGaSe<sub>2</sub> crystal, in-phase terahertz radiation is generated across the entire length of this 485 μm-thick crystal. Therefore, this crystal can be utilized as a source of broadband terahertz radiation in areas such as medicine and security.

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.
