(Just a quick report)
The fine alignment of the ABSL laser injection was successfully done.
I was able to see the DRMI fringings at the AS camera. The ABSL beam is injected from the AS port, therefore what I saw on the camera was the reflection back from the interferometer.
(Things to be done)
- A beat-note setup on the PSL table.
- Refinement of the mode matching. The beam spot on the AS camera is a bit bigger, so I should more tightly focus the injected beam.
- Fine alignments will be done tomorrow
