We experimentally demonstrate synchronization of chaos in one-way coupled He-Ne lasers with optical feedback. We observe different types of synchronization such as identical synchronization, inverse synchronization, and random amplification. These dynamics are maintained only for a short duration of several hundred milliseconds. We also observe generalized synchronization of chaos by using one master and two slave lasers. The generalized synchronization is achieved for a long duration of tens of seconds under injection locking. The generalized synchronization is always maintained while the injection locking is achieved.
我们通过实验证明了具有光学反馈的单向耦合氦氖激光器中的混沌同步。我们观察到了不同类型的同步，如完全同步、反同步和随机放大。这些动力学仅在几百毫秒的短时间内得以维持。我们还通过使用一个主激光器和两个从激光器观察到了混沌的广义同步。在注入锁定条件下，广义同步在长达数十秒的时间内得以实现。在实现注入锁定的同时，广义同步始终得以维持。
