Narrowband biphotons with polarization-frequency
... Our experimental configuration is illustrated in Fig. 1(a). We produce narrowband photon pairs from SFWM in lasercooled 85 Rb atoms in a three-dimensional magneto-optical trap driven by two coherent (pump and coupling) laser fields [24]. The atomic cloud has a diameter of about 1.3 mm. The relevant ...
