I've started a spreadsheet for the BHD optics specifications and populated it with my best initial guesses. There are a few open questions we still need to resolve, mostly related to mode-matching:
- PR2 replacement: What transmission do we need for a ~100 mW pickoff? Also, do we want to keep the current curvature of -700 m?
- LO mode-matching telescope: What are the curvatures of the two mirrors?
- Lenses: We have six of them in the current layout. What FLs do we need?
The spreadsheet is editable by anyone. If you can contribute any information, please do! |
