摘要:

首次提出了一种基于薄片技术的双梳状激光器及其在直接频率梳状光谱中的应用。我们的Yb:YAG薄盘双梳系统的峰值功率(0.6 MW)和平均功率(12 W)比以前的任何系统都高出一个数量级以上。该方案允许在操作期间容易地调整重复频率差。在没有任何主动稳定的情况下,记录超过10 μs的时域信号足以在傅立叶变换后分辨单个梳状线。该演示将使双梳系统在研究实验室的实际应用中得到更广泛的采用。它的简单性和紧凑性,特别是用于实现三梳和多梳系统,并转换到仍然覆盖不足的紫外和真空紫外范围,使其成为一个有前途的下一代技术。

英文摘要:

For the first time to our knowledge, a dual-comb laser based on thin-disk technology and its application to direct frequency comb spectroscopy are presented. The peak power (0.6 MW) and the average power (12 W) of our Yb:YAG thin-disk dual-comb system are more than one-order-of-magnitude higher than in any previous systems. The scheme allows easy adjustment of the repetition frequency difference during operation. A time-domain signal recorded over 10 μs without any active stabilization was sufficient to resolve individual comb lines after Fourier transformation. The demonstration should enable a wider adoption of dual-comb systems towards practical applications in research laboratories. Its simplicity and compactness especially for the realization of tri- and multi-comb systems and conversion into the still poorly covered UV and VUV ranges makes it a promising next-generation technology.
