研究目的
Demonstrating an all-fiber mode-locked laser based on Mamyshev mechanism operating at 1550 nm for high-energy pulse generation.
研究成果
The all-fiber mode-locked laser based on Mamyshev mechanism demonstrated stable, high-energy pulse generation at 1550 nm without the need for external seed pulses or auxiliary starting arms. The laser achieved a maximum pulse energy of ~18 nJ and maintained single-pulse operation over a wide range of pump powers, making it a high-quality and cost-effective source for various applications.
研究不足
The maximum pulse energy was limited by the available pump power. The study suggests that higher energy mode-locked pulses could be obtained with higher pump power.
1：Experimental Design and Method Selection:
The experiment utilized a linear-cavity laser based on the Mamyshev mechanism, incorporating self-phase modulation and offset spectral filtering for mode locking.
2：Sample Selection and Data Sources:
The laser cavity included a tunable filter, an optical circulator, a wavelength division multiplexer, erbium-doped fiber, an optical coupler, an optical filter, and a broadband optical reflector.
3：List of Experimental Equipment and Materials:
Equipment included a tunable filter, optical circulator, wavelength division multiplexer, erbium-doped fiber, optical coupler, optical filter, broadband optical reflector, and a 1480 nm Raman fiber laser for pumping.
4：Experimental Procedures and Operational Workflow:
The laser was pumped with up to
5：7 W of power, and mode locking was initiated by adjusting the polarization controller or shaking the fiber. Output was monitored using an optical spectral analyzer, oscilloscope, and RF analyzer. Data Analysis Methods:
Output spectra, pulse widths, and energies were analyzed as functions of pump power.
