Weak Seeding Broadens DSR Energy Window by Suppressing Multipulsing in CGLE Laser Model
The preprint demonstrates deterministic single-pulse selection via weak seeding in a DSR laser model governed by the cubic-quintic CGLE. Shared mathematics with fluid pattern formation suggests immediate applicability to coherent-structure control in industrial flows. Evidence comes from extensive stochastic numerics rather than analytic proof or experiment.
Next steps include mapping the laser-derived thresholds onto laboratory fluid experiments, such as cylinder wakes or channel flows seeded by localized acoustic or electromagnetic perturbations, to test whether the predicted energy window enlargement appears at Reynolds numbers below 10^3. Successful transfer would directly inform low-power control strategies for HVAC noise reduction and drag mitigation within the next 12-18 months.
