Quick comparison between two working points in a FP-cavity (using analysis.action.Parallel)

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 […]
