AI 中文摘要
近期在掺镱锁模光纤激光器中观察到的复制对称性破缺（RSB）揭示了准锁模（QML）状态下的玻璃态行为。在此，我们研究这种行为是仅限于特定的激光器实现，还是代表了锁模系统的一种更普遍的特征。通过利用Parisi重叠参数和Pearson相关系数分析光谱强度涨落的统计相关性，我们研究了两种钛蓝宝石激光系统：一个自制谐振腔和一个商用激光器。在两种情况下，QML状态下均观察到清晰的RSB特征，而在放大自发辐射（ASE）和标准锁模（SML）状态下则恢复了复制对称行为。这些结果证明了RSB在钛蓝宝石激光器中的出现，并支持将QML状态解释为光子玻璃态。结合之前在掺镱光纤激光器中的观察，这些发现表明QML动力学与RSB之间的联系可能是锁模激光系统的一个普遍特征。
英文摘要
Recent observations of replica symmetry breaking (RSB) in ytterbium-based mode-locked fiber lasers have revealed glassy behavior in the quasi-mode-locked (QML) regime. Here, we investigate whether this behavior is restricted to a specific laser implementation or represents a more general feature of mode-locked systems. By analyzing statistical correlations of spectral intensity fluctuations through the Parisi overlap and Pearson correlation parameters, we study two Titanium:sapphire laser systems: a homemade cavity and a commercial laser. In both cases, clear signatures of RSB are observed in the QML regime, while replica-symmetric behavior is recovered in the amplified spontaneous emission (ASE) and standard mode-locked (SML) regimes. These results demonstrate the occurrence of RSB in Titanium:sapphire lasers and support the interpretation of the QML regime as a photonic glassy phase. Together with previous observations in ytterbium-based fiber lasers, these findings suggest that the connection between QML dynamics and RSB may be a general feature of mode-locked laser systems.
