高斯束谐振系统对遗迹高频引力波方向的选择效应

Selective Effect to Direction of Relic High Frequency Gravitational Waves on Gaussian Beam Resonance System

高斯束谐振系统为早期宇宙遗留的随机高频引力波的探测开启了一个非常重要的窗口．本文指出,当入射引力波的传播方向与高斯束不同时,高斯束谐振系统产生的一阶扰动光子流将降低几个数量级,即高斯束谐振系统只对沿某一特定方向传播的高频引力波产生响应．因此,高斯束谐振系统对高频引力波的传播方向具有良好的选择效应．

Gaussian beam resonance system （GBRS） opens a very important window for detection of relic stochastic high frequency gravitational waves （HFGWs） of early universe. The results of calculation show that the first- order perturbation photon flux produced by GBRS will reduce several orders of magnitude, when the propagation direction of GWs is different from that the positive direction of the symmetrical axis of Gaussian beam, namely GBRS only responses to relic HFGWs which （that） propagate along certain a specific direction. Therefore, GBRS has a good selective effect to the propagation direction of relic HFGWs.
