Summary
Controlling noise filtering in fiber lasers can influence the probability of specific states appearing, impacting the emergence of extreme rogue waves. This research explores noise amplitude and cutoff frequency effects.
Area of Science:
- Nonlinear dynamics
- Laser physics
- Complex systems
Background:
- Rogue waves in fiber lasers are linked to system parameter perturbations.
- Multistate intermittency describes systems switching between different states.
Purpose of the Study:
- Investigate control of state probabilities in multistate intermittency using low-pass noise filtering.
- Analyze conditions for extreme pulse emergence in erbium-doped fiber lasers.
Main Methods:
- Numerical analysis of noise filtering effects.
- Experimental investigation in an erbium-doped fiber laser system.
Main Results:
- State probabilities depend non-monotonously on noise amplitude and cutoff frequency.
- Low-pass noise filtering can control the likelihood of specific system states.
Conclusions:
- Noise filtering is a viable method to influence stochastic dynamics in complex systems like fiber lasers.
- Understanding these dynamics is crucial for managing extreme events and optimizing laser performance.
