We present experimental and numerical evidence of synchronization of burst events in two different modulated CO2 lasers. Bursts appear randomly in each laser as trains of large amplitude spikes intercalated by a small amplitude chaotic regime. Experimental data and model show the frequency locking of bursts in a suitable interval of coupling strength. We explain the mechanism of this phenomenon and demonstrate the inhibitory properties of the implemented coupling.
我们给出了两种不同调制二氧化碳激光器中突发事件同步的实验和数值证据。突发在每个激光器中随机出现，表现为被小幅度混沌状态穿插的大幅度尖峰序列。实验数据和模型表明，在合适的耦合强度区间内突发会出现频率锁定。我们解释了这种现象的机制，并展示了所实现耦合的抑制特性。
