Abstract

本发明公开了一种适用于冷原子实验的前级原子预冷却系统,与实验腔体连通,其包括:玻璃腔体,用于接收待冷却原子;真空腔体组件,用于维持玻璃腔体与实验腔体之间的压强差,并为冷却后的原子团提供传输通道;水平方向冷却装置,用于将水平冷却激光扩束为椭圆形光斑并发射出去以对原子团水平方向上的温度进行冷却;竖直方向冷却装置,用于将竖直冷却激光扩束为椭圆形光斑并发射出去以对原子团竖直方向上的温度进行冷却;梯度磁场线圈组件,用于提供梯度磁场;原子团推送组件,设置在玻璃腔体一侧,用于发射一组推送激光将冷却后的原子团从玻璃腔体中推送至实验腔体中。本发明能够使原子团的温度更低、光学厚度更高、原子通量更大。;本发明公开了一种适用于冷原子实验的前级原子预冷却系统,与实验腔体连通,其包括:玻璃腔体,用于接收待冷却原子;真空腔体组件,用于维持玻璃腔体与实验腔体之间的压强差,并为冷却后的原子团提供传输通道;水平方向冷却装置,用于将水平冷却激光扩束为椭圆形光斑并发射出去以对原子团水平方向上的温度进行冷却;竖直方向冷却装置,用于将竖直冷却激光扩束为椭圆形光斑并发射出去以对原子团竖直方向上的温度进行冷却;梯度磁场线圈组件,用于提供梯度磁场;原子团推送组件,设置在玻璃腔体一侧,用于发射一组推送激光将冷却后的原子团从玻璃腔体中推送至实验腔体中。本发明能够使原子团的温度更低、光学厚度更高、原子通量更大。;本发明公开了一种适用于冷原子实验的前级原子预冷却系统,与实验腔体连通,其包括:玻璃腔体,用于接收待冷却原子;真空腔体组件,用于维持玻璃腔体与实验腔体之间的压强差,并为冷却后的原子团提供传输通道;水平方向冷却装置,用于将水平冷却激光扩束为椭圆形光斑并发射出去以对原子团水平方向上的温度进行冷却;竖直方向冷却装置,用于将竖直冷却激光扩束为椭圆形光斑并发射出去以对原子团竖直方向上的温度进行冷却;梯度磁场线圈组件,用于提供梯度磁场;原子团推送组件,设置在玻璃腔体一侧,用于发射一组推送激光将冷却后的原子团从玻璃腔体中推送至实验腔体中。本发明能够使原子团的温度更低、光学厚度更高、原子通量更大。

Other Abstract

The invention discloses a preceding-stage atom pre-cooling system suitable for a cold atom experiment, which is communicated with an experiment cavity and comprises a glass cavity used for receiving atoms to be cooled; the vacuum cavity assembly is used for maintaining the pressure difference between the glass cavity and the experiment cavity and providing a transmission channel for the cooled atomic group; the horizontal cooling device is used for expanding the horizontal cooling laser beam into an elliptical light spot and emitting the elliptical light spot to cool the atomic group in the horizontal direction; the vertical direction cooling device is used for expanding the vertical cooling laser beam into an elliptical light spot and emitting the elliptical light spot to cool the atomic group in the vertical direction; the gradient magnetic field coil assembly is used for providing a gradient magnetic field; and the atomic group pushing assembly is arranged on one side of the glass cavity and is used for emitting a group of pushing laser to push the cooled atomic group from the glass cavity into the experiment cavity. According to the method, the temperature of an atomic group can be lower, the optical thickness is higher, and the atomic flux is larger.
