研究目的
Investigating the generation of power-scaled dissipative soliton with a compact ?ber-based all-normal-dispersion laser con?guration.
研究成果
The study successfully demonstrates the generation of power-scaled dissipative soliton with a compact ?ber-based laser con?guration, achieving the shortest pulse duration among reported all-?ber pumped Watt-level mode-locked ?ber lasers. The findings highlight the potential for further advancements in materials science to enhance mode-locked ?ber lasers.
研究不足
The study is limited by the technical constraints of the compact ?ber-based laser con?guration and the potential for optimization in ?ltering bandwidths and laser performance.
1：Experimental Design and Method Selection:
The study utilizes a 10-μm core diameter, ?ber-based, compact-sized, and low-cost all-normal-dispersion laser con?guration. The methodology includes the use of different ?ltering bandwidths to investigate laser performance.
2：Sample Selection and Data Sources:
The experiment uses a 10-μm core diameter, double-clad ?ber as the gain medium.
3：List of Experimental Equipment and Materials:
The setup includes a multimode laser diode (LD), a pump-signal combiner, Yb-doped ?exible double-clad ?ber, a polarizing beam splitter (PBS), a polarization-sensitive isolator (PS-ISO), a half-wave plate (HWP), and two quarter-wave plates (QWP).
4：Experimental Procedures and Operational Workflow:
The experiment involves coupling pump power into the highly doped, ?exible, double-clad ?ber through the pump-signal combiner. The PBS, birefringent plate (BFP), and the PS-ISO realize the chirped pulse spectral ?ltering-based dissipative soliton-forming mechanism.
5：Data Analysis Methods:
The study analyzes the laser performance in terms of spectra distribution, temporal characteristic, average power, and stability.
