参考铯原子钟的光学频率链已用于直接测量电四极杆的频率，该电四极杆允许在单个捕获的激光冷却 88 Sr+ 离子中以 445 THz 进行 5 s S 1/2 2− 4 d D 5/2 2 跃迁。已确定过渡频率 f S− D= 444 779 044 095.4 kHz，估计标准不确定度为 0.2 kHz。当前实验中探测离子跃迁的固有偏移经计算为 10−15 水平。
An optical frequency chain referenced to a Cs atomic clock has been used to measure directly the frequency of the electric quadrupole allowed 5 s S 1/2 2− 4 d D 5/2 2 transition at 445 THz in a single, trapped, and laser cooled 88 Sr+ ion. A transition frequency, f S− D= 444 779 044 095.4 kHz with an estimated standard uncertainty of 0.2 kHz has been determined. Intrinsic offsets of the probed ion transition in the current experiment are calculated to be at the 10− 15 level.
