Abstract

We have firstly demonstrated a free-running, polarization-multiplexed, single-cavity dual-comb fiber laser with a simplified linear-cavity configuration. The repetition rate of the laser is around 86.3 MHz while its repetition rate difference can be tuned from 1.0 kHz to 1.8 kHz. Then, it is verified that the ranging precision by this dual-comb source can be optimized according to the carrier frequency of the beat interferogram signal. When the interferogram’s carrier frequency is centered at 26 MHz by tuning the mode-locking state of the laser, a ranging precision of 392 nm is achieved with 67 ms averaging time. In further, we have found the radio frequency spectrum of the interferogram signal is hardly influenced by the change of the repetition rate difference, which leads to the consistency of the distance measurement. This result indicates dual-comb ranging by this compact single-cavity fiber laser is potentially robust to environmental disturbance and this laser source can be a good candidate for other dual-comb applications.

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
