WebApr 1, 2014 · Abstract We have set up a coherent population trapping (CPT)-based magnetometer prototype with the D1 line of ⁸⁷Rb atoms. The dichromatic light field is derived from a fiber electro-optic modulator (FEOM) connected to an external cavity laser diode. A CPT resonance signal with a 516 Hz linewidth is observed. http://www.globalauthorid.com/WebPortal/AuthorView?wd=GAID10358688&rc=1S123S
