【摘要】 激光自诞生以来就在众多领域中有着广泛应用，激光碎石技术就是其中之一。相比目前激光碎石技术的“金标准”钬激光器，掺铥碎石光纤激光器在近些年不断发展，而且逐步被证明可实现更快的碎石速率与粉末化碎石、产生较小的碎石反推力、允许更高的液体灌溉速率等手术优点，同时整机系统支持免水冷工作、高电光效率运转、全光纤高效耦合以及大幅度体积缩减，因此受到了越来越多的关注。本文从连续性、准连续型和纳秒短脉冲型掺铥光纤激光器三个角度出发，详细总结了掺铥光纤激光器的部分重要研究进展及其在碎石领域的研究，介绍了掺铥光纤激光器用于碎石的优势与原理，并展望了未来研究的方向和挑战。更多还原

【Abstract】 Laser lithotripsy is one of the many fields in which laser has been used since its inception. The thulium-doped lithotripsy fiber laser has evolved in recent years and has gradually been proven to achieve faster lithotripsy rates with powdered lithotripsy, generate less lithotripsy counter-thrust, allow higher liquid irrigation rates, and other surgical advantages, while the whole system supports water-free operation, high electro-optical efficiency operation, efficient allfiber coupling, and substantial volume reduction. Therefore the thulium-doped lithotripsy fiber laser has attracted increasing interest. In this paper, some important research progresses of thulium-doped fiber lasers are summarized in detail from three aspects: continuous-wave, quasi-continuous-wave, and nanosecond short-pulsed thulium-doped fiber lasers, and the applications in the field of lithotripsy are introduced. We present the advantages and principles of thuliumdoped fiber laser for lithotripsy and look forward to the directions and challenges for future research.更多还原
