The invention relates to a temperature stable electro-optic modulation device. The temperature-stable electro-optic modulation device includes an electro-optic modulator and a temperature interferometer, and the temperature interferometer includes an inner layer temperature control component and an outer layer temperature control component; the inner layer temperature control component is configured to form at least one built-in All or part of the inner layer container of the electro-optic modulator, the inner layer container at least provides stability to the temperature of the electro-optic modulator; the outer layer temperature control component is configured to form at least one embedded in the inner layer An outer container of all or part of a container, said outer container providing at least stabilization of the peripheral temperature of said inner container. The present invention sets up two temperature control structures inside and outside. The temperature control structure of the inner layer is mainly used to reduce the overall temperature of the electro-optic modulator, and the temperature control structure of the outer layer is mainly used to provide a constant external temperature for the modulator. The function can effectively improve the reliability and stability of the modulation effect of the electro-optic modulator.
Description
technical field [0001] The invention relates to the technical field of cold atom interferometers, in particular to a temperature-stable electro-optic modulation device. Background technique [0002] An electro-optic modulator is a commonly used optoelectronic device in cold-atom interferometers to generate two coherent laser beams. The electro-optic modulator is developed based on the electro-optic effect of the electro-optic crystal. The refractive index of the electro-optic crystal is affected by the crystal temperature. When the crystal temperature changes, the modulation effect of the electro-optic modulator will be greatly affected, causing the cold atom interferometer to pull out. Mann optical power and phase fluctuations will further affect the measurement accuracy of the interferometer. Therefore, it is necessary to precisely control the temperature of the electro-optic modulator during the operation of the cold atom interferometer. At present, there are very few r...
