Hi! We are observing an excess of frequency noise on the sidebands, which is apparently due to laser noise being shifted by the modulation through an EOM We would like to try to simulate this, adding some frequency noise on the laser and modulating it. In particular, we would like to add some noise around […]
This is a simple snippet of code showing how to change the Schnupp asymmetry in the finesse3 virgo model. The process is quite straightforward and is based on simply changing the length of the space between the beamsplitter and one of the compensation plates. An important step to follow the Schnupp asymmetry change is to […]
We found an issue in the function DARM_RF_to_DC(dc_offset = XX), The DC offset given as an input to the function was wrongly dived by two, within the function . This has been fixed by Riccardo.
For an offset of about 1~5mW we can still lock the ITF in a working point, we know for a very small offset this does not holds i.e. 0.1mW, but when an offset of 0.2mW is selected it crashes.
