Comment to Placed the optics for WFSf3 on MIFREFL table (29823)

Thank you for checking WFS-HWP, Ikeda-san.

Since it was confirmed that WFS-HWP was turned, WFS-HWP was turned so that the input power of the WFS is the same power.

Details

Unlike in klog28114, it was 0.65W in front of WFSHWP, so we made the power in front of shatter into 1.71(0.65W/0.75W*2) times in this time. 
we made the WFS1 and WFS2 input power into 0.87(0.65W/0.75W) times from the power in front of WFSHWP.

  Position klog28114 Calculated from klog28114. This time after HWP turning note
Before WFSHWP 0.750W   0.65W  
In front of shatter 58.3mW 98mW (klog28114*1.71) 0.097W =③+④
BS3 trans     53.0mW =⑤+⑥
BS3 refl     50.2mW =⑦+⑧
PZT1 refl 22.2mW 19.24mW (klog28114*0.87) 19.3mW =WFS1 input power
PZT1 refl 36.3mW 31.46mW (klog28114*0.87) 32.5mW =WFS2
PZT3 refl     24.6mW =WFS3
PZT3 trans     25.8mW =WFS4
