摘要: The phenomenon of drift instability was recently identified in optics and hydrodynamics by several authors. Here we show that also the temporal analogon exists. It can be found all types mode-locked lasers may described as two coupled clocks, i.e., actively mode locked, synchronously pumped, certain passively (additive-pulse) lasers. relevant parameter is a timing mismatch obtained, e.g., cavity length misadjustment. Locking over finite interval observed, turns out to crucially important for generation stable pulses. Based on dedicated experiments numerical simulations explain analogy, threshold behavior locking.
