“…However, these essential cage modules introduce approximate 40% power loss for each sub-ring in the fiber-space-fiber coupling process, even under the optimized collimation state and the minimized intracavity loss with wave plates. Moreover, either the collimation or the wave plates should always be adjusted away from the optimized state to maintain the power balance between the dual-rings [29].…”

“…To ensure a free but recoverable switching among the mode-locking states of the dual-ring integrated laser, a cage module is added in each sub-ring to adjust the intracavity loss. The evolution of the mode-locking status of this dual-ring laser has been experimentally explored in our previous works, reported in [29]. Although only dual-comb generation was analyzed, the law of mode-locking evolution for this dual-ring laser is invariable.…”

“…Based on our previous studies of the dual-ring mode-locked laser [29], we have found that it is an effective and simple way to achieve variable repetition rates. Similar dual-ring lasers were reported in [26,27] to generate different types of pulses, e.g., dissipative and conventional solitons or vector and scalar pulses.…”

The tri-comb-based multi-heterodyne detection technique has been proven to be a powerful tool for precision metrology, e.g., laser ranging and spectroscopy. However, in existing tri-comb generation methods, it is difficult to provide a large and variable difference in tri-comb repetition rates. In this paper; we propose a multidimensional multiplexing mode-locked laser based on a dual-ring integrative structure. Combining the dimensions of sub-ring multiplexing and wavelength multiplexing, two modes of tri-comb generation can be achieved with the dual-ring single cavity laser. The generated combs are identified based on the relative intensity of the pulse trains and optical spectrum, and the repetition rates of dual-combs from the same sub-ring are distinguished based on dispersion analysis. With repetition rates of approximately 47 MHz and 49.6 MHz, the minimum and maximum repetition rate difference of the generated tri-comb can be changed from 2.38 kHz and 2.59526 MHz to 2.74 kHz and 2.59720 MHz merely by switching the operation mode of the dual-ring integrated mode-locked laser. The obtained results indicate that our method can offer a powerful scheme for future multi-comb generation and its application in multi-heterodyne detection-based laser ranging and spectroscopy.

Single-cavity, dual-comb lasers are those specially designed mode-locked lasers that can emit more than one, asynchronous ultrashort pulse trains with stable repetition frequency difference between them. Unlike the long-studied, widely-used femtosecond lasers generating one stable pulse train, systematic investigation on them and their potential dual-comb applications only began, based on the fiber laser platform, around a decade ago, despite sporadic and limited reports of similar lasing phenomena since the beginning of the mode-locked laser studies. From a historic perspective, the birth of this novel technology is the lucky outcome of the timely collision of perpetual search for novel pulsing laser dynamics and concerted pursuit of open-minded solutions for out-of-lab dual-comb systems in the 2010s. In this review article, first, the current schemes to implement single-cavity dual optical frequency comb fiber lasers and their applications are summarized, based on the concept of multiplexed mode-locked lasers. The characteristics of reported single-cavity, dual-comb fiber lasers are discussed as well as their applications in spectroscopy, ranging, Terahertz (THz) spectroscopy, and asynchronous optical sampling (ASOPS). Finally, the more recent development of single-cavity, multi-comb lasers is presented.
