研究目的
Investigating the experimental observation of dual-wavelength dissipative soliton operation in a fiber laser with net anomalous cavity dispersion without mode locking.
研究成果
The experimental demonstration of dual-wavelength dissipative soliton operation in a fiber laser without any mode locker in the cavity is a clear indication of dissipative solitons in anomalous-dispersion-cavity fiber lasers. Various states of dual-wavelength dissipative soliton operations were achieved, showing robustness and resilience to collisions.
研究不足
The study does not fully understand the dual-wavelength operation mechanism of the fiber laser, suspecting an artificial spectral filter formation in the cavity. The technical constraints include the need for careful tuning of the intracavity PC and pump power to achieve desired soliton operations.
1：Experimental Design and Method Selection:
The study involves a ring laser cavity that is dispersion-managed, consisting of erbium-doped fiber and single-mode fiber with net anomalous dispersion. The laser is pumped by a high-power Raman fiber laser source.
2：Sample Selection and Data Sources:
The fiber laser setup includes a ~3-m erbium-doped fiber and an ~12-m single-mode fiber.
3：List of Experimental Equipment and Materials:
Components include a fused 1480 nm/1550 nm wavelength division multiplexer (WDM), a 10% output coupler, a polarization controller (PC), and an isolator.
4：Experimental Procedures and Operational Workflow:
The laser's pump power is increased, and the paddles of the intracavity PC are tuned to achieve dual-wavelength CW emission and subsequently soliton emission.
5：Data Analysis Methods:
An optical spectrum analyzer and a 33-GHz oscilloscope with photodetectors monitor the optical spectrum and soliton pulse evolution.
