PAYMENT DEVICE light shifts in frequency standard based on atomic transitions

摘要

The invention relates to frequency and time metrology, and in particular, to a method for compensation of light shifts in frequency standards based on atomic transitions. Object of the utility model, the suppression effect (compensation) for light Stabilizability frequency shift at low requirements to the operating mode and parameters of the laser radiation. The problem is solved in that the compensation device light shifts in frequency standards based on atomic transitions, comprising: a precision oscillator, whose output frequency ω _clock is stable and unmoved for the clock signal; an additional generator, the output of which is formed ω _comp frequency to compensate for shifts of light; laser optical frequency is modulated at radio frequencies at a frequency corresponding to half the frequency position of the vertex of reference resonance ω _with a modulation index, providing maximum contrast fiducial resonance, the value of the modulation frequency is the sum of frequencies ω _clock and ω _comp of the precision and the additional generator, respectively; a modulator adapted to modulate the intensity of said reference frequency resonance; cell with atomic gas, which receives the laser light output from intensity modulator; a photodetector for detecting the laser radiation transmitted through said cell; a synchronous detector for binding said narrowband frequency ω _clock to the reference resonance apex; and other synchronous detector for broadband tuning frequency ω _comp of said additional generator to the top of the same reference resonance modulated light shifts. 2 ZP f ly-4-yl.
