利用共振辐射压力获得准单一速度原子束

An Approach Monochromatic Velocity Atomic Beam Obtained by Resonance-Radiation Pressure

报道了利用行波场的并振辐射压力获得准单一速度原子束的实验研究结果，并进行了理论分析．实验上利用外入射失谐为－１００ＭＨｚ行波光声并振作用原子束可使准单—速度原子束偏转１．７ｍｍ，速度宽度小于５８ｍ／ｓ．

The experimental observation of defleCtion of an approach monochromatic velocity atomic them uSing travel-wave field resonance-radiation PreS8ure is reported and the theory analysis is Presented in this peper. In experiment, the deflection distance of the approach monochromatic velocity atomic beam is about 1. 7 mm when the atomic beam interacts with a oblique incident travel-wave laser beam with detheing-100 MHz and the △v is less than 58 m/s.
