Relative to the incoherent optical feedback, the incoherent optical feedback is less sensitive to frequencydetuning, so it can deduce requirements of system to working conditions.
相对于相干光反馈而言，非相干光反馈因其对位相的变化不敏感，因而可降低系统对工作环境的要求；

The squeezing of the single mode cavity field is influenced by the driving field Rabi frequency, the cavity-mode frequencydetuning from that of a coherent external field and the cavity decay rate.
It is shown that the quantum entanglement state will stay in the maximally entangled state for a long time when the detuning is equal to rabi frequency.
