We have achieved dual synchronization of chaos in two pairs of one-way coupled Nd:YVO4 microchip lasers, using only one transmission channel, by experiment and numerical calculation. We observed the individual synchronization of chaos in each pair of two lasers by adjusting the optical frequencies for injection locking between the corresponding pairs. The achievement of dual synchronization is dependent on the injection-locking condition, which is different from the locking condition for a single pair of lasers because of the presence of an additional injection signal from the master laser of the other pair.
通过实验和数值计算，我们仅使用一个传输通道，在两对单向耦合的Nd:YVO₄微芯片激光器中实现了混沌的双重同步。我们通过调整相应对之间用于注入锁定的光频率，观察到了每对两个激光器中混沌的单独同步。双重同步的实现取决于注入锁定条件，由于存在来自另一对主激光器的额外注入信号，该条件不同于单对激光器的锁定条件。
