Continuing with referring to Fig. 1, for the signal-to-noise ratio for improving entire inactive type rubidium atom frequency scale, using the method for optical pumping.
But pumping light will cause87The movement of Rb atomic transition frequency, i.e., so-called optical frequency shift, optical frequency shift are alternation optical frequency for its essence
The average effect for the AC Stark effect that electric field generates.Pumping light pair87The level shift formula formula (1) of Rb atomic ground state:And formula (2):Wherein, P is electric dipole moment
Operator, E are the complex amplitudes of optical electric field, and 1/ γ is | the service life of α > excitation state, EαAnd EiThe respectively energy of excitation state and ground state level
Amount.Optical frequency shift and energy shift have following relationship, such as formula (3):
From the above equation, we can see that optical frequency shift is directly proportional to light intensity, while related with spectral profile.From (3) formula: if pumping light
For monochromatic light, and ω=ω justαi, then will not cause optical frequency shift；If ω > ωαi, then cause negative frequency shift；If ω < ωαi,
Then cause positive frequency displacement；If ω and ωαiFall far short, then caused by frequency shift amount absolute value and | ω-ωαi| inversely.

The superposition of a plurality of spectrum line.Some frequency component generates positive optical frequency shift, another portion within the scope of pumping light optical lineshape function
Crossover rate component generates negative optical frequency shift.The frequency displacement of 0-0 transition caused by this nonmonochromatic light is frequency caused by many a monochromatic light
The superposition of shifting.Therefore, for Rb atom frequency marking, keep the spectrum line style of pumping light and light intensity constant, to reduction optical frequency shift pair
The influence of frequency marking aging drift is critically important.A kind of device based on raising optical pumping efficiency that this patent proposes can use

Rubidium atom in interior integrated filtering resonance bubble is using relevant microwave pulse resonance.Pass through in a pumping light pulse described
When integrated filtering resonance bubble, the rubidium atom in the integrated filtering resonance bubble is concentrated on five sub- energy levels of F=2.Two
Relevant has the microwave pulse of certain time interval to act on rubidium atom, and microwave frequency is equal to the 0-0 transition of rubidium atomic ground state
Frequency.When second microwave pulse effect, the spectrum lamp module is lighted, on keeping microwave pulse exposure basis, by micro-
Processor is sampled light detection.After completing light detection, microwave pulse and the spectrum lamp module are closed, and quantum is rectified a deviation
Information passes to microwave interrogation signals generation circuit, to complete the servo of complete machine.
Continuing with referring to Fig. 1, entire improvement project principle is as shown in Figure 1: on conventional atom frequency marking technical solution basis
On, spectrum lamp, integrated filtering resonance bubble, microwave control inquiry signaling module are relied on, following improvement is done: (1) being added in spectrum lamp module
Magnetic hyperfine ingredient optical filter；(2) spectrum lamp energisation mode uses square-wave voltage energisation mode；(3) to being placed in resonant cavity
Integrated filtering resonance bubble in rubidium atom using relevant microwave pulse resonance.
In order to in spectrum lamp module, plus magnetic hyperfine ingredient optical filter, pulse optical pumping, coherent pulse microwave are total
Vibration, light detection are explained in detail, now respectively in spectrum lamp module, plus magnetic hyperfine ingredient optical filter, pulsed light is taken out
Fortune, coherent pulse microwave resonance, light detection carry out following detailed description respectively:
(1) in spectrum lamp module plus magnetic hyperfine ingredient optical filter.One Rb atom frequency marking adjusted, quantum
The optical frequency shift of physical part can be with set to zero, its frequency is to the minor change of pump intensity with regard to insensitive in this way.But it is real
The size of optical frequency shift is not only directly proportional to the pump intensity being irradiated in absorption bubble on border, and with the pumping that is irradiated in absorption bubble
The line shape function relationship for transporting light spectrum line is very close: some frequency component produces within the scope of pumping light spectrum line line shape function
Raw positive optical frequency shift, another part frequency component generate negative optical frequency shift.So-called to be adjusted to zero optical frequency shift, only actually means to take out
Transport the sum of zero of optical frequency shift caused by each section frequency component within the scope of light spectrum line shape function.So total optical frequency shift is zero
The result that actually positive and negative two big optical frequency shift amount is added.Under these conditions, if Pump intensity changes
The line shape function of spectrum line does not change, then can still keep optical frequency shift is zero, but if the line shape function generation of spectrum line is micro-
Small variation, it is easy to total optical frequency shift be caused to be not zero.And rubidium spectral lamp, in long-term work, not carrying on a shoulder pole Pump intensity can occur
Small variation, and small variation can also occur for pumping light spectrum line shape function.
Spectrum lamp is in long-term work, due to the variation of its working condition, the factors such as the consumption of bulb 87Rb, light
It changes by force, influences the stability indicator of frequency marking.By experiment, the complete machine output frequency parameter insensitive to light intensity can be found
Point.The selection of light intensity and the temperature selection of integrated filtering resonance bubble are combined together consideration by us, and bubble temperature appropriate is selected to make
Optical frequency shift minimizes.It is selected when experiment under different light intensity, by changing the temperature of integrated filtering resonance bubble, measurement complete machine frequency
The output of rate obtains the zero light intensity frequency displacement bubble temperature of our needs.As shown in Figure 2.Wherein, abscissa is integrated filtering resonance bubble
Temperature, ordinate are difference frequency value.It can be seen from the figure that complete machine exports when integrated filtering resonates bubble temperature selection in T=T0
Frequency is unrelated with the spectrum strong I of light, the T0 i.e. bubble temperature of zero light intensity frequency displacement.Precisely, it is bent to change overall frequency measured by light intensity
Line can not be met at completely a bit, often meet at a small delta-shaped region, therefore can not completely eliminate optical frequency shift pair
The influence of stability.In the case where having selected optimal integrated filtering resonance bubble temperature, influence of the light intensity to frequency can be done
To 1 × 10-12/1%, i.e. light intensity variation 1%, then causing the variation of frequency is 1 × 10-12.Certainly for different rubidium clock systems
System, light intensity is different to the influence degree of frequency, and the same system to work in different conditions would also vary from.
It is poor caused by the variation of chamber temperature by figure it will be seen that for of different sizes, the identical pumping light of spectrum line style
Frequency value change be it is different, the slope of 70% light intensity curve is smaller than the slope of 100% light intensity curve in figure, i.e., for
70% light intensity is small when the variation of chamber temperature, caused frequency displacement is than 100% light intensity.If the selection of light intensity further reduces
(such as 50% light intensity, 30% light intensity ...) can obtain more preferably slope light intensity according to the trend in figure, but be due to considering
The signal-to-noise ratio of system, it is impossible to select the light intensity of very little, buffer gas matches in the bubble that needs to resonate by change integrated filtering at this time
Than and pressure obtain the light intensity of zero-temperature coefficient.
In scheme, the hyperfine ingredient optical filter of a magnetism is added in the rear class of spectrum lamp transmitting optical path, selection is different
Optical filter, can control spectrum lamp light intensity needed for above-mentioned theory, it is more important to mention that improve pumping light spectrum linear,
To make pumping light spectrum it is linear be around centre frequency it is full symmetric, the generation of optical frequency shift can be further decreased.

There is the microwave pulse of certain time interval to act on rubidium atom, microwave frequency is exactly equal to rubidium atomic ground state 0-0 transition
