Dual-comb spectroscopy has been extensively studied in various applications, and recently, single-cavity dual combs have emerged as a compelling option for simplifying measuring systems. This review summarizes the progress and distinctive advantages of single-cavity dual comb lasers, including their implementation techniques and typical applications. The principles of optical frequency comb and dual-comb spectroscopy are introduced, and an outlook on the development of single-cavity dual combs is presented.
Dual-comb spectroscopy as an emerging tool for spectral analysis has been investigated in a wide range of applications, including absorption spectroscopy, light detection and ranging, and nonlinear spectral imaging. Two mutually coherent combs facilitate high-precision, high-resolution, and broadband spectroscopy. Recently, dual combs generated from a single cavity have become compelling options for dual-comb spectroscopy, enabling huge simplification to measuring systems. Here, we review the progress of single-cavity dual comb lasers in recent years and summarize the distinctive advantages of single-cavity dual combs. First, the principles of optical frequency comb and dual-comb spectroscopy are introduced in time and frequency domains. Then, the implementation techniques and typical applications of single-cavity dual comb lasers are discussed, including directional multiplexing, wavelength multiplexing, polarization multiplexing, and space multiplexing. Finally, an outlook on the development of single-cavity dual combs is presented.
