| Abstract(in English) | We have experimentally demonstrated chaos synchronization in two Nd:YVO_4 microchip lasers by using optical injection. Since the condition of the chaos synchronization is strongly dependent on the injection locking range, it is easy to synchronize chaos of the master laser with that of unauthorized lasers if the optical frequencies are matched to each other. To improve the disadvantage, we have proposed a new chaos-synchronization method based on incoherent feedback to the pumping power by using the value proportional to the difference between the peak heights of the electrical amplitude in two laser outputs. We can achieve narrow tolerable region of chaos synchronization even if there exists parameter mismatching between the two lasers, because this method requires the matching of population inversion between the two lasers instead of electrical fields without injection locking effect. |
