论文摘要
在实际锁定激光器上控制载体包络阶段（CEP）几乎长时间尺寸对于超快光学和精度计量学中的现实世界应用至关重要。我们提出了一种混合解决方案，该解决方案结合了一种馈送前向技术，以稳定快速时间尺度中的相位偏移和一种反馈技术，该反馈技术解决了缓慢变化的干扰和锁定带宽限制，与增益媒体相关的较长的上层寿命。我们在ER中实现了杂种稳定系统：YB：玻璃模式锁定激光器，并以14 mrad（1 Hz至3 MHz）的整合相位噪声（1 Hz至3 MHz）展示了75小时的稳定化，对应于载体与封装抖动。此外，我们研究了环境因素（例如湿度和压力）对系统长期稳定性和性能的影响。
Controlling the carrier envelope phase (CEP) in mode-locked lasers over practically long timescales is crucial for real-world applications in ultrafast optics and precision metrology. We present a hybrid solution that combines a feed-forward technique to stabilize the phase offset in fast timescales and a feedback technique that addresses slowly varying sources of interference and locking bandwidth limitations associated with gain media with long upper-state lifetimes. We experimentally realize the hybrid stabilization system in an Er:Yb:glass mode-locked laser and demonstrate 75 hours of stabilization with integrated phase noise of 14 mrad (1 Hz to 3 MHz), corresponding to around 11 as of carrier to envelope jitter. Additionally, we examine the impact of environmental factors, such as humidity and pressure, on the long-term stability and performance of the system.
