Temporarily Unlocking Phase-Locked Laser for Chirping via External Signal

[ultracoldmol]

I am working on optical phase-locking a laser to a frequency comb using an IQ and PID module as described in the paper. I need to temporarily unlock the phase lock in response to an external signal, allowing me to chirp the laser, and then reestablish the phase lock. How can I achieve this?

I think this is the same question as #501 and unfortunately it is not implemented. You could have a python routine checking the level of a signal but you would have quite big and random delay due to ethernet communications.

@michaelcroquette Do you think the delay would decrease if one would execute the python routine on the RedPitaya itself without using a Ethernet connection?

It should but I have never tried it.
