Accurate and efficient external calibration, available in real-time within a targetless environment, remains a significant challenge due to the inherent inhomogeneous reflectance, density distribution, and small FOV of Non-Repeat Scanning (NRS) LiDAR system data, these issues bring difficulties for subsequent applications in areas such as simultaneously localization and mapping (SLAM) and autonomo...Show More
The evolutions and properties of solitons in a thulium-doped fiber laser hybrid mode-locked by the coaction of nonlinear polarization rotation (NPR) and a semiconductor saturable absorber mirror (SESAM) have been numerically investigated. The mode-locking threshold can be greatly reduced by inserting a SESAM into the NPR-based mode-locked laser cavity. The features of solitons in this hybrid mode-...Show More
