Abstract:
    The utility model discloses a coherent layout number confinement cold atom clock. The coherent layout number confinement cold atom clock is composed of a vacuum pump, a vitreous plenum chamber, a high power semiconductor laser, a low power semiconductor laser, a narrow linewidth semiconductor laser, a high frequency acousto-optic cell, a signal reception processor, a crystal voltage-controlled oscillator and a frequency accumulated frequency multiplier. The vacuum pump is connected with the vitreous plenum chamber. The high power semiconductor laser is connected with the enjailing luminous beam. The low power semiconductor laser is connected with the re-pumping luminous beam. The narrow linewidth semiconductor laser is respectively connected with the high frequency acousto-optic cell, the cooupled with luminous beam and the detective luminous beam. The crystal voltage-controlled oscillator is respectively connected with the signal reception processor and the frequency accumulated frequency multiplier. This utility model is provided with simple structure, and improves accuracy and stability of the atom clock, and it can be miniaturized and commercialized.
