We introduce a new stabilization scheme providing a pair of high-power, carrier-envelope-offset (CEO) frequency-stabilized, broadband, asynchronous frequency combs operating at 3.3 μm. The two channels, each with 100 mW average power and originating from a single synchronously pumped optical parametric oscillator, share all the components for midinfrared generation and CEO-frequency detection, and can be stabilized independently at repetition frequencies up to 5 kHz apart. This unique source is fully compatible with midinfrared dual-comb spectroscopy, and the approach can be readily extended to other wavelengths.
我们介绍了一种新的稳定化方案，提供了一对高功率、载波包络偏移（CEO）频率稳定、宽带、异步频率梳，工作在 3.3 μm。这两个通道，每个通道的平均功率为 100 mW，来自单个同步泵浦光参量振荡器，共享所有中红外产生和 CEO 频率检测的组件，并且可以在高达 5 kHz 的重复频率下独立稳定。这种独特的光源完全兼容中红外双梳光谱学，并且该方法可以很容易地扩展到其他波长。
