“…The GVD had very little impact on the temporal pulse shape affecting mainly the width of the pulse spectrum pedestal. Longer NALM loop length leads to smaller peak power, and thus wider pulse width at the same pump power [31].…”

“…Recently, few techniques were utilized to generate ultrashort pulses below 1 μm: femtosecond Yb-doped fiber laser amplification with optical parametric oscillator [16], [17], nonlinear frequency shift in a high-nonlinearity fiber [18], [19], frequency doubling of the 1.8-1.9 μm ultrafast laser emission [20], fiber-optic Cherenkov radiation technique inside a short piece of photonic crystal fiber [21] and direct generation using the neodymium-doped fiber (Nd-fiber) quasi-three-level F3/2 -4 I9/2 transition [22]- [31]. The last one is preferred due to its robustness and simplicity.…”

Moving the fiber laser emission to the region below one micron may provide a cheaper, more compact and robust alternatives to the existing solid state lasers. Here, for the first time we report a neodymium mode-locked fiber laser emitting at 905 nm in the all-fiber polarization maintaining configuration. We obtain a self-starting pulse generation in nonlinear amplifying loop mirror (NALM) cavity configuration. To suppress a dominant emission at 1064 nm corresponding to a 4-level laser scheme, we use an active fiber -920/1064 division multiplexeractive fiber sandwich-like sequence in the NALM loop. A rectangular shape dissipative soliton had nJ energy, 30 pm spectral width and 80 ÷ 430 ps width linearly depending on the pump power. Excellent agreement with numerical simulation allowed us to recover pulse shape and width for the pulses out of autocorrelation window.

“…Considerable effort has been expended to develop ultrafast fiber lasers at ~900 nm [3]- [7]. Qian et al [3] demonstrated a passively mode-locked neodymium-doped oscillator featuring a W-type fiber operating at 930 nm with a pulse energy of 2.2 nJ and a pulse duration of 126 fs.…”

“…Recently, Chen et al [5] demonstrated 4.4-nJ 114-fs pulses at ~910 nm using an optimized Nd-doped fiber amplifier, as well as 17-nJ 220-fs pulses at 930 nm [6]. Becheker et al [7] have reported a dissipative soliton fiber laser with a maximum energy of 20 nJ at 927 nm. However, the gain bandwidth limits the spectrum bandwidth of the mode-locked pulse to ~20 nm, which can only support a transform-limited pulse width of 65 fs, assuming a Gaussian profile.…”

Fiber-optic Cherenkov radiation (FOCR) is a promising nonlinear process that is widely used for nonlinear wavelength conversion. In this study, an all-fiber 920-nm femtosecond pulse source is experimentally demonstrated by using Cherenkov radiation. The 4-nJ 150-fs 1550-nm amplified seed pulse source ensures highly efficient 920-nm pulse generation. Cherenkov radiation is stimulated by inputting the high-energy ultrashort pulse to a highly nonlinear fiber. The dispersion values of the highly nonlinear fiber (HNLF) are carefully chosen to generate CR pulses at 920 nm. The generated pulse has a 150-pJ single pulse energy and a 232-fs pulse duration. The typical 30-nm bandwidth can support a sub-50-fs transformlimited pulse duration. The pump current can be adjusted to tune the central wavelength of the pulse source over 905-930 nm. This very simple approach can generate 920-nm femtosecond pulses. The wavelength range is useful for a wide range of applications, such as two-photon microscopy (TPM) in bio-imaging and so on.

“…In particular, a new operation regime, dissipative soliton resonance (DSR), was proposed to overcome the difficulty of passive mode locking in a large normal-dispersion fibre cavity [26][27][28] . Based on the DSR regime,~10 μJ high-energy DSR pulses in a normaldispersion Er/Yb codoped fibre laser at 1.55 μm have been successfully achieved 29 , and a strong normal-dispersion Nd-doped fibre laser at the 927 nm short wavelength has also been mode locked 30 . Furthermore, if one can well combine the DSR regime with the abovementioned progress in the visible region, then a breakthrough in visiblewavelength passively mode-locked fibre lasers can be expected.…”

Towards visible-wavelength passively mode-locked lasers in all-fibre format

Mode-locked fibre lasers (MLFLs) are fundamental building blocks of many photonic systems used in industrial, scientific and biomedical applications. To date, 1-2 μm MLFLs have been well developed; however, passively modelocked fibre lasers in the visible region (380-760 nm) have never been reported. Here, we address this challenge by demonstrating an all-fibre visible-wavelength passively mode-locked picosecond laser at 635 nm. The 635 nm mode-locked laser with an all-fibre figure-eight cavity uses a Pr/Yb codoped ZBLAN fibre as the visible gain medium and a nonlinear amplifying loop mirror as the mode-locking element. First, we theoretically predict and analyse the formation and evolution of 635 nm mode-locked pulses in the dissipative soliton resonance (DSR) regime by solving the Ginzburg-Landau equation. Then, we experimentally demonstrate the stable generation of 635 nm DSR mode-locked pulses with a pulse duration as short as~96 ps, a radio-frequency signal-to-noise ratio of 67 dB and a narrow spectral bandwidth of <0.1 nm. The experimental results are in excellent agreement with our numerical simulations. In addition, we also observe 635 nm noise-like pulse operation with a wide (>1 nm) and modulated optical spectrum. This work represents an important step towards miniaturized ultrafast fibre lasers in the visible spectral region.
