Embodiment Construction
[0088] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0089] The atomic beam generating device for an atomic chip provided by the present invention includes an atomic source, a vacuum chamber, a two-dimensional fine-tuning table, a magnet (permanent magnet or magnetic field coil) and an internal and external optical system.
[0090] Such as figure 1 As shown, the three-dimensional magneto-optical trap formed by cooling lasers 1, 2, 13, 15, 18, 19 and the second pair of anti-Hertz coils 14 captures and cools the atom source steam beam 17 ejected from the hot atom source nozzle, Wherein the cooling laser 15 is that the cooling laser 1 passes through a 1 / 4 wave plate positioned outside the vacuum chamber and a mirror ( figure 1 Not shown in ) the reflected cooling laser that obtains, cooling laser 18 is that cooling laser 2 passes through a 1 / 4 wave plate and a mirror ( figure 1 not shown...
