“…Figure 2 shows a schematic diagram of the experimental apparatus. The experiments were performed with light from an 894 nm diode laser (Toptica DL100L, distributed feedback laser) whose frequency was actively locked to the F g = 4 → F e = 3 hyperfine transition of the cesium D 1 line using a Doppler-free dichroic atomic vapor laser lock (DAVLL) technique [11,12]. The laser beam was carried by a polarization maintaining fiber to the experiment proper and split by a polarizing beam splitter cube into two beams of approximately equal intensity.…”

Abstract:We report on a study of polarization-modulation experiments on the 4 → 3 hyperfine component of the D 1 transition in Cs vapor contained in a paraffin-coated cell. The laser beam's polarization was switched between left-and right-circular polarization at a rate of 200 Hz. Variations of the transmitted light power were recorded while varying the amplitude of a transverse magnetic field. The power shows electromagnetically induced transparency (EIT) resonances when the atomic Larmor frequency matches a harmonic of the modulation frequency. We made a quantitative study of the resonance amplitudes with square-wave modulations of various duty cycles, and find an excellent agreement with recent algebraic model predictions.

“…The beams are generated by two semiconductor lasers (Toptica, model TA100). Both lasers are stabilized to the atomic transition by the Dopplerfree dichroism method [8]. One of the lasers produces the repumping light for both MOTs, tuned to the F g = 1 − F e = 2 transition.…”
