Ultrafast fiber laser delivering conservative, dispersion-managed, and dissipative solitons
摘要: A thulium-doped ?ber laser, delivering the temporal solitons, has been proposed with a carbon nanotubes saturable absorber. By adjusting the dispersion design in the laser cavity, the proposed laser can generate three types of solitons, which are conservative soliton (CS), dispersion-managed soliton (DMS), and dissipative soliton (DS), respectively. The experimental results show that, for the ?rst time to the best of our knowledge, the autocorrelation traces of CS, DMS, and DS are in good agreement with hyperbolic secant curve, Gaussian curve, and super-Gaussian curve, respectively. DS with the broad spectral bandwidth of 45.3 nm is emitted from the cavity while the dispersion is adjusted to 0.005 ps2.

All-Fiber Saturable Absorbers for Ultrafast Fiber Lasers
摘要: The past decade has witnessed tremendous achievements of ultrafast ?ber laser technologies due to rapid developments of saturable absorbers (SAs) based on, in particular, nanomaterials such as 0D quantum dot, 1D carbon nanotubes, 2D layered materials, and 3D nanostructures. However, most of those nanomaterials-based SAs are inevitably absence of the high damage threshold and all-?ber integration, therefore challenging their applications on highly integrated and high-energy pulse generations. Recently, the real all-?ber SAs based on the nonlinear multimodal interference (NLMMI) technique using multimode ?bers are demonstrated to overcome the above limitations. In this review, a detailed summary of the recent advances in NLMMI-based all-?ber SAs is provided, including the fundamental theory, implementation scenarios, and ultrafast ?ber lasers of the all-?ber SAs, covering wide wavelength range of 1, 1.55, and 2 μm. In addition to the state-of-the-art overview, optical rogue waves in the all-?ber SA-based ultrafast ?ber laser are extensively analyzed, which reveals the laser physics behind the dynamics from low-energy to high-energy pulses and directs the design of high-energy ultrafast ?ber lasers. The conclusions and perspectives of the all-?ber SAs are also discussed at the end.
