Abstract

fetched live from OpenAlex

We report on the development of diode-pumped high power continuous-wave (CW) and ultrashort pulse Yb:KGW lasers for applications in nonlinear multimodal microscopy. In the CW regime we generated 5W of average output power from a simple three-mirror cavity, with 22% of optical-to-optical conversion efficiency. The CW laser was used as a platform for development of a high power mode-locked oscillator. We achieved 2.3W of average output power in the mode-locked regime with ~210 fs duration pulses centered around 1047 nm at a repetition rate of 97 MHz. This corresponds to 24 nJ of energy per pulse and 114 kW of peak power. The demonstrated laser will be used in second- and third-harmonic generation microscopy of biological samples.

Full frame distilled prediction

Teacher imitation

Not 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.
