“…Examples are the sensitivity measurement of the absorption rate rather than the magnitude1, the non-linear spectroscopy and multiphoton microscopy, which require a high-intensity beam to stimulate the nonlinear phenomena2, and time-resolved photoluminescence3. Most tunable mode-locked fiber lasers are in the 1 μm and 1.5 μm regime and a few in 2 μm regime, in which Tm- or Ho-doped fiber is used as the gain medium45678910. Since Tm- or Ho- doped fiber lasers operate at the eye-safe regime and have broader emission spectra, they are particular important for medical and military applications having potentially a widely tunable range.…”

We demonstrated a widely tunable Tm-doped mode-locked all-fiber laser, with the widest tunable range of 136 nm, from 1842 to 1978 nm. Nonlinear polarization evolution (NPE) technique is employed to enable mode-locking and the wavelength-tunable operation. The widely tunable range attributes to the NPE-induced transmission modulation and bidirectional pumping mechanism. Such kind of tunable mode-locked laser can find various applications in optical communications, spectroscopy, time-resolved measurement, and among others.

“…Mode-locked fiber lasers with stable dual wavelength outputs in a robust configuration are attractive for many applications such as ranging systems, communication, pump-probe spectroscopy, microwave photonics, and terahertz generation, etc [9]. Dual wavelength mode-locked fiber lasers have been reported in a thulium doped fiber (TDF) laser [10], erbium doped fiber (EDF) lasers [9,11,12], and Ytterbium doped fiber (YDF) lasers [13][14][15][16][17][18]. However, in most of these studies, secant hyperbolic or Gaussian-type ultrashort pulses in the picosecond duration have been reported, where mainly naturally formed birefringence of a single mode-fiber is used for lasing wavelength selection, no specific wavelength selecting component is incorporated in the cavity.…”

Dual-wavelength rectangular pulses in a mode-locked ytterbium-doped fiber laser

et al. 2020

We demonstrate dual wavelength rectangular pulses in an ytterbium-doped fiber laser in a simple, all-fiber standing wave cavity configuration. The laser cavity consists of a nonlinear optical loop mirror as a saturable absorber at one end and two fiber Bragg gratings at the other end at wavelengths of 1025 and 1055 nm. There are three distinct regimes of operation in the cavity with an increase in the pump power, one where only 1025 nm wavelength pulses appear, then both 1025 and 1055 nm pulses are supported in the cavity after that, only 1055 nm wavelength pulses are present in the cavity. In the intermediate pumping regime, two sets of pulses are supported in the cavity. These pulses move in the cavity at different speeds and on the cross-over there is no interaction in the pulses. The mode-locked pulses at the 1025 nm wavelength are polarized, whereas pulses corresponding to 1055 nm are nearly unpolarized. Pulses corresponding to both the wavelength bands exhibit a dissipative soliton resonance signature. The laser generates 60 mW total average output power at the maximum pump power of 260 mW at a ∼1.8 MHz repetition rate. The presented cavity mechanism can be utilized to generate various dual-or multi-wavelength mode-locked pulses.

“…If Tm-or holmium-(Ho-) doped fiber is used as the gain medium, the emitting wavelength of the fiber lasers will be near 2 µm. However the tunable multi-wavelength mode-locked fiber lasers are mostly reported in the 1 µm and 1.5 µm regime and a few near 2 µm regime [10][11][12][13][14][15][16][17][18][19][20][21]. The tunable range of 2 µm mode-locked all-fiber lasers is limited to 50 nm [22].…”
