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.
In a perfectly aligned and matched Fabry-Perot cavity, one of the zero-crossings of an RF-demodulated error signal such as the PDH error signal corresponds to the cavity resonance peak. When imperfections are added, the two working points (peak resonance and zero-crossing of the error signal) can diverge. In this example we show how, a progressive […]
