“…Recently, Soltanian et al 18 successfully realized self-starting mode-locked pulses with low repetition rate. Qi et al 19 reported a semiconductor saturable absorber mirror (SESAM) mode-locked ytterbium-doped fiber laser (YDFL) with the pulse duration of 57 ps and the bandwidth of 41 pm at the repetition rate of 1.04 MHz. In terms of theoretical research, researchers numerically simulated the effects of dispersion on pulse evolution and output characteristics of passive mode-locked thulium-doped fiber laser.…”

.Mode-locked erbium-doped fiber lasers (EDFL) with the low repetition rate and high pulse energy play an important role in many fields, such as micromechanical processing, ophthalmic surgery, biological sample detection, and LiDAR detection. However, in the 1550 nm band, due to the anomalous dispersion and nonlinear effects of erbium-doped fiber lasers (EDFLs), it is difficult to achieve mode-locked pulses especially in long cavities, which brings many difficulties to engineering applications. We analyze and simulate the pulse formation and evolution process in a mode-locked EDFL at a low repetition rate of sub-megahertz. The results show that by decreasing the gain or increasing modulation depth/saturation light intensity of saturable absorber in a specific range, a stable single-pulse mode-locked state can be achieved. Then a multipulse mode-locked state can be achieved by gradually increasing the gain or decreasing the saturation light intensity. In addition, the pulse width can be compressed by adjusting the second-order dispersion coefficient. The numerical simulation results are instructive for the design and development of EDFL at a low repetition rate of sub-megahertz.
