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.
