“…Er:fiber lasers based on NALM have the advantages of low-noise operation, self-starting, and an all-polarization-maintaining structure. In addition, there is no risk of optical-induced damage [30,[77][78][79][80][81][82].…”

Optical frequency combs have emerged as a new generation of metrological tools, driving advancements in various fields such as free-space two-way time–frequency transfer, low-noise microwave source generation, and gas molecule detection. Among them, fiber combs based on erbium-doped fiber mode-locked lasers have garnered significant attention due to their numerous advantages, including low noise, high system integration, and cost-effectiveness. In this review, we discuss recent developments in erbium-doped fiber combs and analyze the advantages and disadvantages of constructing fiber combs utilizing different erbium-doped mode-locked fiber lasers. First, we provide a brief introduction to the basic principles of optical frequency combs. Then, we explore erbium-doped fiber combs implemented utilizing various mode-locking techniques, such as nonlinear polarization rotation (NPR), real saturable absorber (SA), and nonlinear amplifying loop mirror (NALM). Finally, we present an outlook on the future perspectives of erbium-doped fiber combs.

“…This also means that the reflectivity of the continuous wave is higher than that of the pulsed laser, which leads to achieve mode-locking operation difficultly. When the initial phase shift is −π/2, the reflectivity of the NALM increases with the nonlinear phase shift in the cavity at this point, which facilitates the self-started mode-locking [25].…”

We demonstrate an all-polarization-maintaining (PM) ytterbium (Yb)-doped fiber laser with a figure-of-9 structure to generate mode-locked pulses with high single pulse energy and high repetition frequency. By exploiting the nonlinear amplifying loop mirror (NALM), a stably self-started mode-locking is achieved with a spectrum bandwidth of 13 nm and a pulse duration of 4.53 ps. The fundamental frequency is 97.966 MHz at the maximum output power of 143 mW in single pulse mode-locked operation, corresponding to the single pulse energy is 1.46 nJ. The output pulses maintain both high repetition frequency and high single-pulse energy. Moreover, the superior stability of the mode-locked operation was measured in 45 minutes. This laser oscillator can be an ideal seed source for applications such as high-energy amplifiers.

“…Examples include nonlinear polarization rotation (NPR) 9,10 and nonlinear amplifying loop mirrors (NALMs). 11,12 One issue for NPR is that the mode-locking operation cannot be self-started and fine-adjustment of polarization directions is constantly required due to environmental sensitivity. 13,14 For NALMs, the repetition rate of mode-locked pulses is typically below 10 MHz owing to their long cavity length.…”
