引力波影响激光腔中电磁波的传播，调制发射光子的频率。我们利用这一效应，通过光学精密光谱学在100kHz至100MHz范围内搜索高频引力波。我们的限制首次约束了该频率范围的大部分。我们讨论了该技术未来的改进，预计可将灵敏度提高八个数量级，并将频率覆盖范围至少扩展到1GHz。
英文摘要
Gravitational waves affect the propagation of electromagnetic waves in laser cavities, modulating the frequency of emitted photons. We use this effect to search for high-frequency gravitational waves between 100 kHz and 100 MHz using optical precision spectroscopy. Our limits constrain much of this frequency range for the first time. We discuss future improvements of the technique, which we expect to enhance the sensitivity by eight orders of magnitude, and to extend the frequency coverage up to at least 1 GHz.
