瑞士的科研人员首次在无外加放大情况下得到了单脉冲能量超过10mJ的Yb:YAG圆盘飞秒激光器。高能飞秒脉冲是许多科学研究和工业应用的关键设备。在这些应用中,常见方法是利用激光放大系统,但重复频率却被限制在千赫兹以内,这影响了信噪比,也限制了其在材料加工方面的应用。其他实现重复频率在兆赫兹的微焦脉冲, For the first time, researchers in Switzerland obtained Yb: YAG disk femtosecond laser with single pulse energy exceeding 10 mJ without amplification. High-energy femtosecond pulses are the key devices for many scientific research and industrial applications. In these applications, a common approach is to use a laser amplification system, but the repetition rate is limited to kilohertz, which affects the signal-to-noise ratio and limits its application in material processing. Other micro-focus pulses that achieve repetition rates in megahertz,
