Quantronix
Calibration is done after each main tuning of lasers, mainly when lamps are replaced: every ~2000hrs (80days).
1) Measure YLF power.
2) Measure TiS power, main λ
3) Alignment of the main fibre output
4) Short run internal trigger: report and replace pulse center timing inside laser_h.cfg file.
