Large-Bandwidth, Low-Noise Phase-Lock of External Cavity Diode Lasers for Atom Interferometers

摘要

We demonstrate a laser system consisting of an external cavity diode laser phase-locked to another free-running one at a wavelength of 780nm using an intracavity electro-optic phase modulator. A bandwidth of >10MHz and a phase noise of <-100dBc/Hz at 1MHz from the carrier are achieved.
