【摘要】 基于囚禁离子与驻波激光场相互作用,应用驻波光场的相位调制的方法,我们提出了一种制备离子振动压缩态的新方法.研究了压缩振幅与调制振幅的关系.我们发现:适当选择调制振幅,可把离子制备在最佳压缩振动态上,并且它们的产生伴随着自发辐射的相消.提出了一种实验构想,并进行了讨论.更多还原

【Abstract】 A new method to prepare dark squeezed states of the motion of a trapped ion that interacts with a standing wave light field has been proposed.This method is based on modulation of the phase of the standing wave field.The dependence of the squeezed amplitude on the modulation amplitude is investigated.Choosing the appropriate modulating amplitude,we can produce the best squeezed vibrational state of the ion and find that its generation is companied by cancellation of the emitted fluorescence.In addition,an experiment configuration about its preparation is proposed and discussed.更多还原
