我们建造了一个马赫-曾德型原子干涉仪,用锂的超声束进行操作。原子衍射利用激光驻波上的布拉格衍射。与一阶衍射,我们的设备给出了一个大的信号和一个非常好的条纹对比度(74%),我们相信这是有史以来最高的观察与热原子干涉仪。该装置将应用于高灵敏度的测量。
We have constructed an atom interferometer of the Mach–Zehnder type, operating with a supersonic beam of lithium. Atom diffraction uses Bragg diffraction on laser standing waves. With first-order diffraction, our apparatus has given a large signal and a very good fringe contrast (74%), which we believe to be the highest ever observed with thermal atom interferometers. This apparatus will be applied to high-sensitivity measurements.
