- We will have free discussion time after each talk, which is not shown in the table
Minues
OMC
- Wedge angles of OMC1, OMC2 matters?
Should we include the thickness (and wedge) of OMC1? (Somiya-san) Gouy phase difference between V and H is <1 deg, which should be negligible.
- (Hiro-san)The slope (from HOM 0 -8 of the experiment) maybe reflecting the spatial abbreviation of the test masses having longer wavelength more than short wavelength
(Akutsu-san) Aso-san’s document: this. The current OMC is base on the **-R500.*** files. It is nice to confirm it with him! In my memo, with this document, I did double-checking of the Aso-san’s ray-trace with another commercial simulator.
GUI
- The windows installation procedure is ready
- (Hiro-san) Can you add mirrors? - No
- We can expand the configuration, such as OMC and IMC.
- (Akutsu-san) Can you change macroscopic lengths? - Yes
Birefringence
Mach-Zhender model to simulate S->S, S->P, P->S, P->P conversion.
- The intuitive understanding of this model is to convert S-P basis to e-o basis (extraordinary and ordinary axes) by the first BS, and covert back to S-P by the second BS.
