Generation of Two Dissipative Soliton Resonance Pulses in an All-Anomalous-Dispersion Regime Thulium-Doped Fiber Laser
摘要： In this paper, we demonstrate experimentally a thulium-doped passively mode-locked figure-of-eight fiber laser to generate dissipative-soliton-resonance (DSR) pulses in an all-anomalous-dispersion regime. And two different DSR pulses are obtained by simply adjusting the polarization controllers. At maximum pump power of 2.4 W, the average power and repetition rate of two DSR pulses is 113.5 mW and 2.532 MHz respectively, corresponding to a pulse energy of 45 nJ. Subsequently, the effect of NALM length on the two DSR pulses is investigated, and pulses with maximum pulse energy of 63 nJ near 2 μm are obtained.

Effect of spectral filtering on pulse duration in dissipative soliton resonance (DSR) regime of modelocked fiber laser
摘要： The effect of spectral filtering on pulse duration in an all-normal-dispersion laser operating in a dissipative soliton resonance (DSR) regime is studied numerically and compared with the results obtained by solving the analytical expressions. It is observed that the spectral filtering reduces the pulse duration in the DSR regime. The numerically simulated trend of the variation of flat-top pulse duration as a function of the gain for different spectral transmission bandwidths of the filter shows good qualitative agreement with the experimental results.

摘要： The generation of square pulses with different wavelengths based on dissipative soliton resonance (DSR) has been investigated in an Yb-doped passively mode-locked fiber laser. By fixing the pump power and changing the orientations of polarization controllers, wavelength-tunable square pulses have been obtained, which demonstrates that the DSR and lasing wavelength are independent of each other.

摘要： In recent years, the popular thulium-doped fiber lasers (TDFL) are expanding their operational wavelength coverage through accessing the 1.7-μm region, where they have previously been hindered by the quasi-three-level nature of TDF emission, which leads to strong re-absorption of short wavelength light. This was driven by a plenty of applications such as deep bio-imaging, spectroscopic analysis and material processing that takes advantages of the third near-infrared (NIR3) optical window (1600–1870 nm) for bioimaging and abundant molecular absorptions in this spectral region. At present, short wavelength TDFLs have been demonstrated to operate in the continues-wave (CW), soliton mode-locking and gain-switching regimes. Here we report a TDFL that demonstrates dissipative soliton resonance (DSR) at 1750 nm with a maximum single pulse energy of 321.2 nJ.

Splitting and Motions of Dissipative Soliton Resonance Pulses in Mode-Locked Fiber Lasers
摘要： We numerically investigated the splitting and motions of dissipative soliton resonance (DSR) pulses in an all-normal-dispersion Yb-doped ?ber laser mode-locked by a non-linear optical loop mirror. At certain values of the system parameters, the initial single Gaussian pulse can evolve into an unstable DSR pulse with several dark solitons inside. After collisions of dark solitons, a big intensity dip occurs at the center of the DSR pulse, leading to the splitting of the DSR pulse. After splitting, the peak-to-peak separation between two DSR pulses increases at ?rst and ?nally reaches a ?xed value of 193 ps, indicating a steady-state multipulse operation The relative motions of separated DSR pulse originate from the phase shift.
