“…For artificial saturable absorbers based on fiber nonlinearity, such as NPR [21] and nonlinear optical/amplifying loop mirrors (NOLM/ NALMs) [17,22], where the transmission function is produced interferometrically, the slope of the transmission curve becomes negative if the pulse power or the fiber length exceed some critical value. Therefore, the generation of solitons with low repetition rate requires fibers with low nonlinearity, as in [13].…”

In the present work we demonstrate a novel single-soliton ultra-low pulse repetition frequency passively modelocked erbium-doped fiber laser. We mitigate the residual linear birefringence of fiber by fiber twist to achieve a strict control of polarization. For mode-locking the nonlinear polarization rotation (NPR) was used. Special technique was applied to reduce the overdriving of NPR that allows the generation of single soliton in ultra-long cavity. The strict control of polarization yields a stable relation between the polarization state of the pulses propagating in the cavity and the regimes of generation. A 192.12-kHz train of soliton pulses was obtained with pulse duration of 4.7 ps at 1560.1 nm, the average power was 29 μW and the estimated peak power was ̴ 30.8 W with an energy of 150.9 pJ.

“…The pulse properties (e.g., broad spectrum, high energy, and outstanding stability) of mode-locked fiber oscillator are crucial to fiber amplifiers because they affect temporal and spectral features of the amplified pulses. Various mode-locking methods have been developed to obtain energetic ultrashort pulses at 1 µm, such as nonlinear polarization evolution (NPE) [18][19][20][21], saturable absorber mirror (SAM) [22,23], NOLM (nonlinear optical loop mirror), and NALM (nonlinear amplifying loop mirror)) [24][25][26].

We demonstrate highly stable mode-locked Yb-doped fiber oscillators using a nonlinear amplifying loop mirror, delivering linearly polarized laser pulses with high energy at a low repetition rate of several MHz. These lasers are composed of polarization-maintaining fibers and fiber-based components without intra-cavity dispersion compensation. The spectral and temporal characteristics are systematically investigated at different repetition rates. Spectral bandwidth of 31 nm is realized in the case of 6 MHz repetition rate, and the pulse energy reaches 10 nJ. A pair of gratings compresses the output pulse to 93 fs. RMS power stability is as low as 0.04% in 10 hours, which shows excellent stability. We believe that this type of fiber oscillator is an ideal seed for further high power amplification.

“…Soliton compression in active fibers [1,2] and dispersion-decreasing fibers (DDFs) [3][4][5][6][7][8] is a wellunderstood effect [9,10]. It is known that the characteristics of compressed solitons can be controlled by tailoring fiber dispersion.…”

Generation of high-repetition-rate, femtosecond, soliton pulse trains through dual-wavelength pumping of a dispersion-decreasing fiber is studied numerically. The achievable shortest pulse width is found to be limited by third-order dispersion that has a significant effect on the pulse-compression dynamics. The output wavelength is red shifted because of intrapulse Raman scattering and depends heavily on third-order dispersion, whose positive values lead to the most red shifted solitons (> 25% of the input pump center wavelength). The proposed scheme allows the generation of ultrashort pulse trains at tunable high repetition rates with a wide range of output wavelengths and pulse durations through dispersion engineering. The resulting frequency combs extend over a wide bandwidth with a tunable spacing between the comb lines. arXiv:1804.03699v1 [physics.optics]
