1.
The wavelength is fixed with this accuracy, while drift is defined as Wavelength stability. The wavelength is specified in air.
2.
The exit window is located optically ~20cm before the laser head shutter.
3.
Predominantly due stray light, fiber coupling will further improve the extinction ratio.
