Abstract

Elliptical Gaussian beam (EGB) has many different physical properties from circular Gaussian beam. In this paper, the transverse energy flux and intensity of one and two coherent EGBs are studied. In our simulation, the transverse energy flux and intensity varying with waist ratio are discussed in detail. It has been found that through increasing the waist ratio, the transverse energy flux after interference would be strengthened significantly. Although the transverse energy flux is much weaker than the longitudinal energy flux, its signal to noise ratio has been verified to be strong enough for detection. Our derivations are still reasonable for another simulation with general experimental parameters. The simulation results are considered to be helpful for some physical experiments using the transverse energy flux of Gaussian beam, such as an important application in electromagnetic response produced by interaction of high-frequency gravitational waves.

椭圆高斯光束的横向能量传播与干涉

椭圆高斯光束(EGB)与圆形高斯光束具有许多不同的物理性质。本文研究了一个和两个相干EGBs的横向能量通量和强度。在我们的模拟中，详细讨论了横向能量通量和强度随腰比的变化。研究发现，通过增大腰比，干涉后的横向能量通量显著增强。虽然横向能量通量比纵向能量通量弱得多，但其信噪比已被证实足以检测。我们的推导对于具有一般实验参数的另一种模拟仍然是合理的。仿真结果对利用高斯光束的横向能量通量进行物理实验，如研究高频引力波相互作用产生的电磁响应具有重要意义。
