我们研究了弱种子、正常色散激光器在耗散孤子共振（DSR）区随机三次-五次复金兹堡-朗道模型中的脉冲数选择。光种子注入抑制了能量依赖的多脉冲产生，并产生非单调的DSR能量窗口。噪声诱导的形成统计并未建立典型的随机共振或从预先存在的孤子中逃逸。弱单色种子的确定性控制在明显更宽的能量窗口内产生持续的单脉冲行为，增强了耗散孤子能量可扩展性和DSR。
英文摘要
We study pulse-number selection in a stochastic cubic--quintic complex Ginzburg--Landau model of a weakly seeded, normal-dispersion laser in the dissipative-soliton-resonance (DSR) regime. Without noise, a single pulse and pulse pairs persist at the same control parameters, and the total energy of an $N$-pulse state follows a ladder constructed from the single-pulse branch. The final energies of noisy trajectories lie close to the same ladder. Multipulsing therefore does not necessarily lose the single-pulse solution. It can reflect which coexisting state the noisy dynamics reaches. Optical seed injection suppresses energy-dependent multipulsing and, at larger seed power, produces a nonmonotonic DSR energy window. An energy--noise scan shows that energy dominates the multipulse probability, whereas additive noise produces only a modest trend common to all energies, without a noise optimum. The noise-induced formation statistics therefore do not establish canonical stochastic resonance or escape from a pre-existing soliton. Coherent control by a weak monochromatic seed extends predominantly single-pulse operation over a noticeably broader energy window, enhancing dissipative-soliton energy scalability. Within an adiabatic approximation, equal energy sharing among coexisting pulses is stable wherever the single-pulse energy grows less than proportionally with the control energy, as it does over the sampled DSR range. Energy exchange between the pulses then relaxes up to about 200 times more slowly than their total energy.
