Modulation-free laser stabilization technique using integrated cavity-coupled Mach-Zehnder interferometer [PDF]

Nature Communications
Stable lasers play a significant role in precision optical systems where an electro-optic laser frequency stabilization system, such as the Pound-Drever-Hall technique, measures laser frequency and actively stabilizes it by comparing it to a frequency ...
