摘要

摘要:
本文设计并提出了一种被动同步锁模光纤金宝搏188软件怎么用器。该系统采用了双腔结构，并以非线性偏振旋转（NPR）机制作为锁模方式。通过协同控制两个对称子腔内的增益、偏振和光程长度，实现了稳定的同步锁模。实验表明了通过时间延迟线（TDL）可以调节子腔的重复频率，以此来实现同步锁模。实验结果揭示了多个光谱峰和等间距的脉冲序列，证实了在单一重复频率下稳定的多波长脉冲生成。这些研究在光通信、光谱分析和远程传感等领域具有广泛应用，为开发高性能多波长超短脉冲光源奠定了基础。

Abstract:
We designed and investigated a passive synchronized mode-locked fiber laser. The device utilizes a dual-cavity structure driven by the Nonlinear Polarization Rotation (NPR) mechanism. Stable mode-locking is attained by synergistically controlling gain, polarization state, and optical path length in two symmetric sub-cavities. Experiments proved the sub-cavity repetition frequency's tunability via the time delay line (TDL), thereby enabling synchronized mode-locking. The system stably generates multi-wavelength pulses at a single repetition frequency, evidenced by multiple spectral peaks and equidistant pulse sequences. These findings facilitate the development of high-performance multi-wavelength ultrashort pulse sources, crucial for optical communications, spectral analysis, and remote sensing.
