Advanced Fiber Laser Technology and Its Application: 2nd Edition

Dear Colleagues,

Over the past twenty years, investigations into optical fiber lasers and their applications in academic and industrial communities have experienced significant development and attention. Ultra-high power industrial fiber laser with 160 kW output has been commercialized, and the single-frequency fiber lasers with linewidth of several Hz order have also been reported. More encouraging, the pulse width for the pulsed fiber laser could reach a single-cycle level. Moreover, the endlessly emerging new materials, devices, structures, systems, technologies, and principles facilitate the rapid progress of optical fiber lasers and their applications. For example, optical fiber lasers operating at 2 μm waveband are especially suitable for laser medical, free-space optical communication, and coherent Doppler lidar wind detection. The random fiber laser with flexible optical spectral manipulation enables a wide range of applications in high-precision optical fiber sensing, supercontinuum generation, and laser-driven inertial confinement fusion. In addition, LiDAR based on fiber laser, with its superior capabilities in high-resolution three-dimensional spatial mapping and all-weather detection, enables its widespread applications in autonomous vehicle navigation, topographic surveying, and atmospheric environment monitoring. Laser-based SLAM technology, renowned for its high-precision ranging stability and robust pose estimation in feature-scarce environments, facilitates its crucial applications in industrial robotics automation and large-scale augmented reality systems. By integrating lidar scanning with advanced simultaneous localization and mapping algorithms, this system achieves real-time, drift-resistant spatial perception and semantic understanding, which is fundamental for autonomous operational decision-making in complex and unstructured settings. In this context, more and more attention, such as theoretical investigation, experimental exploration, and engineering application, should be paid to optical fiber lasers and their application for researchers and engineering technicians to further enhance the performance of output power, frequency noise, pulse width, linewidth, stability, optical spectral manipulation, etc.
