Example 3 - near unstable cavities¶
This example will simulate what happens as a well designed cavity is pushed close to instability. The example show recipes for the following activities and link to more detailed documentation:
Designing an input telescope
Updating model parameters
Producing a cavity scan
Using a CCD
Locking a cavity

The model¶
We will consider the LIGO Pre-Mode-Cleaner design from [11]. This design is a ring resonator consisting of two flat mirrors and one curved mirror.
Designing an input telescope¶
In this section we will design an input telescope from a selection of standard lab optics.
Plotting a cavity scan¶
In this section we will show how the cavity control signals change as the cavity is pushed closer to instability.
