This project uses Red Pitaya to automate relocking of External Cavity Diode Lasers (ECDL). A special web app makes sure the lasers stay locked in real-time, using signals from the laser cavity or a wavemeter. Originally for the strontium optical tweezers used in quantum computing, it's also handy for things like precise clocks and space missions.
