从理论和实验上研究了相位随机起伏的光波在空间啁啾非线性定向耦合器中的演化。当系统穿过其线性共振时，我们观察到所有相互不相干的波的集体自锁相（自共振），每个波都有自己的泵浦，并同时放大，直到泵浦耗尽。我们表明，在这个系统中的自共振过渡表现出尖锐的阈值，共同的所有相互不相干的波，包括光束。
We study, theoretically and experimentally, the evolution of optical waves with randomly-fluctuating phases in a spatially chirped nonlinear directional coupler. As the system crosses its linear resonance, we observe collective self-phase-locking (autoresonance) of all mutually-incoherent waves, each with its own pump, and simultaneous amplification until the pumps are exhausted. We show that the autoresonant transition in this system exhibits a sharp threshold, common to all mutually-incoherent waves comprising the light beam.
