Paper Abstract

Two longitudinally multimode Febry-Perot diode lasers have been sideband injection-locked to the +1 and -1 sidebands of a 3.4GHz electro-optical modulator (EOM). Optical heterodyne measurement showed that powers of 99.5% of the slave laser could be injection-locked to the +1 or -1 sidebands, and the unselected master laser carrier was suppressed down to -24dB. Generally, the long-term stability and efficiency of the injection-locking to the +1 sideband was worse than the -1 due to the asymmetry of the injection-locking bandwidth. The microwave signal at 6.8GHz had a measured 3dB linewidth of less than 200Hz, without considering the noise contribution by the driving signal of the additional acousto-optical modulator. The proposed method will be used for driving the stimulated Raman transitions in a Rubidium based atom gyroscope.
