使用标准氢氧焰制备的光学纳米光纤在约1385纳米波长处因嵌入的羟基吸收而产生光学损耗，这对利用镱原子实现量子电动力学系统构成了挑战。在此，我们建立了一种在真空条件下通过光纤内导引的激光加热来减少羟基的方法。加热过程中光学纳米光纤的温度通过干涉仪监测透射光的相位移动来估算。结果表明，获得了激光加热使羟基脱附的证据。
英文摘要
Optical nanofibers fabricated using a standard oxyhydrogen flame exhibit optical losses at wavelengths around 1385~nm due to absorption by embedded hydroxyl groups, posing a challenge for the realization of quantum electrodynamics systems using ytterbium atoms. Here, we establish a method for the reduction of hydroxyl groups by heating them with a laser guided within the optical nanofiber under vacuum conditions. The temperature of the optical nanofiber during heating is estimated by monitoring the phase shift of the transmitted light using an interferometer. As a result, evidence suggesting that hydroxyl groups were desorbed by laser heating was obtained.
