half inch surface absorption assuming fused silica substrate
[Marc,Shalika]
It is likely that the half inch substrate is fused silica (n=1.45) so we shifted the imaging unit accordingly (ie by 1.1mm instead of 1.3mm).
We repeated the surface absorption measurements with incident power of the pump between 0.89W to 1.66 W.
Results are in figure 1 and we got 10.5 ppm absorption of the HR surface.

erratum : the correct HR surface absorption should be about 34 ppm (eg peak at z = 32 mm) while the previous estimated value is due to interferences.
