Dual-comb polarization-multiplexing ring-cavity fiber laser for ranging applications

Year: 2025

Type: article

Abstract: We present the design and implementation of a dual-comb polarization-multiplexing ring-cavity fiber laser system tailored for precision ranging applications. This system generates two optical frequency combs within the same cavity enabling enhanced short-term and long-term stability with reduced common noise, while it maintains coherence for more than 125 hours without external stabilization. Also, results show a precision of 340 µm for a 10 ms averaging time with an ambiguity range of 3.8 m. This study confirms the potential of dual-comb polarization-multiplexing systems as a robust and cost-effective solution for precision metrology, LIDAR, and fiber-optic sensing applications.
