Problem
The Redpitaya does not have high enough feedback bandwidth to stabilize narrow line width lasers to ULE cavities, but it has fast digital control for auto-locking. Solution
Interface the redpitaya with an analog lock box that has much higher feedback bandwidth. The redpitaya would tell the analog log box when to lock and when to unlock, but the actual locking would be done fully by the analog lock box.
