Tests of Special Relativity using Laser Spectroscopy (Physics)

高分辨率激光技术和高速 将结合储存环中粒子的分辨率， 验证狭义相对论的正确性。 相对论 多普勒频移实验将测试时间膨胀 光速的各向同性效应。 实验 是基于双光子光谱学，其中一个原子使一个 通过同时吸收来自每一个 两个激光束，一个行进，另一个相反， 原子的方向。 这允许内部取消 经典的一阶多普勒频移， 相对论效应作为主导项。

High resolution laser techniques and high velocity resolution of particles in a storage ring will be combined to test the validity of special relativity. The relativistic Doppler shift experiments will test both the time dilation effect and the isotropy in the speed of light. The experiments are based on two photon spectroscopy, in which an atom makes a transition by simultaneously absorbing a photon from each of two laser beams, one traveling in and the other opposite to the direction of the atom. This allows internal cancellation of the classical first order Doppler shift, leaving the relativistic effects as the dominant term.
