摘要

GHz以上重复频率的超短脉冲锁模激光器正处于快速发展的阶段，预计将为激光技术的应用带来更大的创新与突破。这类激光器不仅在重复频率和脉冲宽度上实现了突破，还在稳定性和输出功率上得到了增强。为了满足各类高端应用需求，研究者们不断探索新的架构和技术，以提高激光系统的整体性能。文章将从高重复频率和超短脉冲这两个重要的激光指标来简要论述近年来国内外的部分研究工作。分别介绍了重复频率GHz以上的超短脉冲锁模光纤激光器和固体激光器的发展状况及应用。

Abstract

Ultrafast pulsed mode-locked lasers with repetition rates above GHz are in a stage of rapid development and are expected to bring greater innovations and breakthroughs to the applications of laser technology. These lasers have not only achieved breakthroughs in repetition rate and pulse width but also enhanced stability and output power. To meet the needs of various high-end applications

researchers are constantly exploring new architectures and technologies to improve the overall performance of laser systems. Some domestic and international research work in recent years will be discussed from the perspective of two important laser indicators: high repetition rate and ultrafast pulses. It will respectively introduce the development status and applications of ultrafast pulsed mode-locked fiber lasers and solid-state lasers with repetition rates above GHz.
