论文摘要
同位素选择性光激发原子对于中性原子，计量学和与捕获离子（包括量子信息处理）的实验非常重要。极化增强的吸收光谱用于将可调外腔激光二极管系统稳定在398.9 nm处，用于同位素选择性光电离子中性YB原子。该光谱技术用于测量来自See中的过渡中的同位素分散分散特征，通过构型ytterbium ytterbium空心电视排放灯。通过放电并通过平衡检测来分析偏振相关的吸收，通过重新反射激光束来实现这种无多普勒二色性极化光谱。使用外部空腔激光二极管的当前调制引起的频率调制诱导的频率调制恢复光谱信号。在这里，我们显示了$^{171} $ yb $^+$，$^{172} $ yb $^+$^+$^+$，或$^{174} $ yb $^+$ $^+$ ions的使用选择性地加载$^{171} $ yb $^+$，$^{171} $ yb $^+$，$^{171} $ yb $^+$，选择性加载$^{171} $ yb $^+$ $^+$ ions。
Isotope selective optical excitation of atoms is important for experiments with neutral atoms, metrology, and work with trapped ions, including quantum information processing. Polarization-enhanced absorption spectroscopy is used to frequency stabilise a tunable external cavity laser diode system at 398.9 nm for isotope selective photoionization of neutral Yb atoms. This spectroscopy technique is used to measure isotope resolved dispersive features from transitions within a see through configuration Ytterbium hollow-cathode discharge lamp. This Doppler-free dichroic polarization spectroscopy is realised by retro-reflecting a laser beam through the discharge and analysing the polarization dependent absorption with balanced detection. The spectroscopy signal is recovered using lock-in detection of frequency modulation induced by current modulation of the external cavity laser diode. Here, we show the use of polarization-enhanced absorption spectroscopy for isotope selectively loading of $^{171}$Yb$^+$, $^{172}$Yb$^+$, or $^{174}$Yb$^+$ ions into an RF Paul trap.
