Abstract

We introduce a new stabilisation 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 mid-infrared 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 mid-infrared dual-comb spectroscopy and the approach can be readily extended to other wavelengths.
