摘要
作为非常典型的高功率固体激光器,“之”字光路板条激光在过去二十年取得了重要的进展,相继发展提出了高平均功率面泵浦板条放大器、多段掺杂板条、高亮度泵浦Yb: YAG板条等新技术。文章对板条激光的技术发展历程进行了回顾、分析和评述,包括它的设计原则、传输功率放大规律以及为了优化性能而产生的各种改进方法。在对板条激光功率定标能力进行一般性讨论基础上,针对性地分析讨论了提高输出功率和改善光束质量的的技术发展趋势,预期高平均功率板条激光技术未来还有相当大的发展空间。
Abstract
As a typical high-power solid-state laser, high average power zigzag slab lasers achieved great progress in past two decades. Which fields got many innovations, such as face-pumped slab amplifier, multi-segment bonded slab structure, high-brightness pumped Yb: YAG slab amplifier and so on. This paper reviewed the technology progress of the slab lasers, including its design principles, transmission power amplification rules and various improvement methods for optimizing performance.On the basis of the general discussion on the laser power calibration capability of the slats, the technical development trend of improving the output power and beam quality was analyzed and discussed. It was expected that there will be considerable development space for high average power slab laser technology in the future.
