Web6. The apparatus according to claim 3, wherein the input beam of light is a frequency modulated laser beam, said apparatus further comprising a photodetector and optical beam splitting means adapted to direct a portion of the pump beam passed through the vapor cell in direction of said photodetector for coherent population trapping measurements. WebThe combination of allowing trapping during a brief time in the fall and restricting trapping to the coast is designed to avoid capture of resident peregrines that belong to the … 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. the vix chart
