同宿混沌的特征是规则的几何轨道发生在不规则的时间。平均重复频率下的相位同步通过控制参数的微小周期性调制来实现。在带反馈的CO_2激光器上进行了实验。设置在同宿混沌发生的参数范围内。调制频率与平均值的任何偏移都会引起长时间的相位滑移。通过基于转差率的符号和幅度的调制频率的缓慢变化来恢复完美的相位同步。卫星同步制度也实现了，与可变数量的同宿尖峰每个周期的调制。
Homoclinic chaos is characterized by regular geometric orbits occurring at erratic times. Phase synchronization at the average repetition frequency is achieved by a tiny periodic modulation of a control parameter. An experiment has been carried on a CO2 laser with feedback. set in a parameter range where homoclinic chaos occurs. Any offset of the modulation frequency From the average induces phase slips over long times. Perfect phase synchronization is recovered by slow changes of the modulation frequency based upon the sign and amplitude of the slip rate. Satellite synchronization regimes are also realized, with variable numbers of homoclinic spikes per period of the modulation.
