摘要 给出了在一静态磁场中强电磁波束对一引力驻波谐振响应的具体形式 ,并得到了相应的扰动解和谐振条件 .我们发现 ,扰动电磁场将包含 3种新的频率成分 :|ωg±ωe|和ωg.在ωe ωg 的情况下 ,扰动电磁场表现为频率为ωe 的电磁波束和频率为ωg 的电磁驻波 ,前者和背景电磁波束具有相同的传播方向 ;而在ωg ωe的情况下 ,所有的扰动电磁场均表现为频率为ωg 的电磁驻波 .谐振响应只发生在ωe=12 ωg和ωe=ωg 两种情况下 ,这时不仅可以产生与背景电磁波束同向和反向传播的一阶扰动电磁能流 ,而且还可以产生传播方向垂直于背景电磁波束的径向和切向一阶扰动电磁能流 .这一效应可望为引力波的电磁探测提供一种新的途径 .此外 ,还讨论了在单光子雪崩效应层次上并在典型实验室尺度范围内 ,显示由h =1 0 -33~1 0 -35 ,λg=0 .
