Paper Abstract

In order to obtain frequency-locked laser beam with widely tunable frequency- offset used in a clod atom interferometer, a frequency stabilization method using a fiber electro-optic modulator (FEOM) is proposed. In this method, the laser passing through a FEOM can be locked with a wide-range frequency-offset, avoiding the frequency and power jitter caused by internal modulation on the current or PZT at the same time. To evaluate the outcome of this method, a beat signal between the frequency-shifted laser and the laser locked by Doppler-free Dichroic Atomic Vapor Laser Lock was measured. The analysis of the experimental results shows that the frequency-offset of the laser beam, with a full width at half maximum less than 1 MHz, can be tuned from 200 MHz to 10 GHz, which successfully meets the requirements of cold atom interferometer.
