摘要
高功率、窄脉宽的超快激光在基础科学研究、精密制造和生物医学等领域扮演着越来越重要的角色。在众多飞秒光源中,激光二极管泵浦的掺镱全固态飞秒激光器具有输出特性优异、结构紧凑、简单可靠、成本低廉等优点,成为超快激光领域的研究热点之一。特别是克尔透镜锁模的掺镱全固态飞秒激光器,有望兼备同时输出百瓦级平均功率、百飞秒级脉冲宽度的能力。本文总结了近年来克尔透镜锁模掺镱块材料全固态激光器在高功率窄脉冲输出方面的研究成果,并对实现百瓦级平均功率、十微焦级脉冲能量和高功率GHz重复频率运转给出了展望和方案设想。
Ultrafast laser with high power and short pulse duration plays a more and more important role in basic scientific researches,precision machining and biomedicine etc.Among the various femtosecond light sources,the laser diode directly pumped Yb-doped all-solid-state bulk femtosecond laser has become one of the research hotspots in the ultrafast laser because of its advantages of compact structure,low cost,reliability and excellent output performance.In particular,the Kerr lens mode-locked Ytterbium-doped allsolid-state femtosecond laser is expected to deliver both an average power of one hundred watts and an pulse duration less than one hundred femtoseconds at the same time.This paper summarizes the research results of Kerr lens mode-locked ytterbium-doped bulky material all-solid-state lasers that generated short pulses with high average power in recent years,and looks forward to it.It also gives a prospect and plan for realizing the mode-locking operations with average power of one hundred watts,pulse energy of ten microjoules and high-power GHz repetition rate,respectively.
