Description

Dual-comb ranging offers high precision and high accuracy distance measurements. However, the application of dual-comb ranging systems is restricted by the complexity of the setup and inherent length ambiguity. Here we present a new and simple approach to increase the ambiguity-free measurement range of dual-comb raining while simultaneously decreasing the complexity by using a single cavity dual-color-fiber laser. By exploiting the intrinsic intensity modulation of our laser we are able to measure distances up to 150 km without ambiguity in a single measurement. The system offers a high data question rate (~2kHz) and the precision and accuracy of dual-comb ranging while requiring only the stabilization of a single repetition rate.
