摘要:

高阶锁模被用来降低参考腔的热噪声极限。通过将激光器锁定到10 cm长的全ULE腔的HG 02模,并在三个独立稳定的激光器中用三角帽法测量其性能,我们证明了分数频率不稳定性为4.9E-16的热噪声限制性能。计算结果与理论模型相吻合。所获得的激光不稳定性将所有ULE短腔结果提高到一个新的低水平。

英文摘要:

Higher-order mode locking has been proposed to reduce the thermal noise limit of reference cavities. By locking a laser to the HG02 mode of a 10-cm long all ULE cavity, and measure its performance with the three-cornered-hat method among three independently stabilized lasers, we demonstrate a thermal noise limited performance of a fractional frequency instability of 4.9E-16. The results match the theoretical models with higher-order optical modes. The achieved laser instability improves the all ULE short cavity results to a new low level.
