本発明は光ポンピング法を用いたガスセル形ルビジウム
原子発振器に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas cell type rubidium atomic oscillator using an optical pumping method.
一般にガスセル形ルビジウム原子発振器内における光−
マイクロ波共鳴部は、その特性上ルビジウムランプ部と
ルビジウムセル部で各別に温度制御が行なわれている。Light in a gas cell type rubidium atomic oscillator -
Due to its characteristics, the temperature of the microwave resonance section is controlled separately for the rubidium lamp section and the rubidium cell section.
すなわちルビジウムランプは充分なスペクトル強度を必
要とするため約１００℃程度の温度で動作させる必要が
ありルビジウムセルは吸収レベルを必要とするため約７
０’Ｃ程度で動作させる必要があるからである。In other words, rubidium lamps require sufficient spectral intensity and must be operated at a temperature of approximately 100°C, while rubidium cells require an absorption level of approximately 7°C.
This is because it is necessary to operate at about 0'C.
このため従来の発振器では２組の温度制御器が用いられ
ている。For this reason, two sets of temperature controllers are used in conventional oscillators.
またランプ部とセル部間相互の熱的な影響を除去するた
めにランプ部とセル部を熱的に遮断する必要がある。Further, it is necessary to thermally isolate the lamp part and the cell part in order to eliminate mutual thermal influence between the lamp part and the cell part.
しかしながら共鳴部を小形に構成しようとする場合、完
全な熱遮断構造を設けることは極めて困難である。However, when trying to make the resonance section compact, it is extremely difficult to provide a complete heat shielding structure.
そのためセル部ｌこはランプ部よりの熱が流入し、画部
分を希望する温度に保つことは容易ではなく、その動作
範囲が制限されてくる。Therefore, heat from the lamp section flows into the cell section, making it difficult to maintain the image section at a desired temperature, which limits its operating range.

方を伝熱材を介して間接的に加熱するように構威しであ
る。In order to achieve the above object, the oscillator according to the present invention combines two temperature controllers conventionally used in the optical-microwave resonant section into one, and winds a heater around one of the lamp section or the cell section. In order to create a temperature difference between the cell portion and the cell portion, they are connected by a heat transfer material that creates a temperature gradient between both ends, and the other end is heated indirectly via the heat transfer material.
このように構成すれば構造は簡略化され発振器の小形化
