Abstract:
We present a method of carrier suppression of a phase-coherent laser beam produced by an electro-optic modulator for coherent population trapping (CPT) clock. To suppress the undesired strong carrier mode of the phase-modulated beam, a Fabry–Perot (FP) cavity is used as an optical filter. The intensity of the carrier mode is reduced by 70% without significant loss of the two first-order side modes for CPT clock. The contrast of the CPT signal is improved by a factor of 1.4 when the carrier-suppressed phase-coherent laser beam is applied to a 87 Rb CPT clock.
