高谐波生成（HHG）广泛用于放大器（接近）红外超快激光脉冲到短波长。为了在此过程中观察到几个MRAD精度。 {2} [3/2] _ {1}在^{132} xe中的110 nm transition我们将其相对精度10^{4}次提高到2.3×10^{ - 10}的值比在涉及HHG之前所显示的要好，并承诺将He^{+}的1S-2S光谱进行基本测试。
High-harmonic generation (HHG) is widely used for up-conversion of amplified (near) infrared ultrafast laser pulses to short wavelengths. We demonstrate that Ramsey-comb spectroscopy, based on two such pulses derived from a frequency-comb laser, enables us to observe phase effects in this process with a few mrad precision. As a result, we could perform the most accurate spectroscopic measurement based on light from HHG, illustrated with a determination of the 5p^{6}→5p^{5}8s^{2}[3/2]_{1} transition at 110 nm in ^{132}Xe. We improve its relative accuracy 10^{4} times to a value of 2.3×10^{-10}. This is 3.6 times better than shown before involving HHG, and promising to enable 1S-2S spectroscopy of He^{+} for fundamental tests.
