Few-layer transition metal dichalcogenides such as molybdenum disulfide (MoS2) present new opportunities for photonic devices. Here, we review recent progress in few-layer MoS2-based nonlinear optics and state-of-the-art pulsed lasers using this new nanomaterial.
We report an environmentally stable nanotube mode-locked fiber laser producing linearly-polarized, nanosecond pulses. A simple all-polarization-maintaining fiber ring cavity is used, including 300 m of highly nonlinear fiber to elongate the cavity and increase intracavity dispersion and nonlinearity. The laser generates scalar pulses with a duration of 1.23 ns at a center wavelength of 1042 nm, with...
We demonstrate a graphene based saturable absorber mode-locked Nd:YVO4 solid-state laser, generating ∼14nJ pulses with ∼1W average output power. This shows the potential for high-power pulse generation.
We report the generation of 420 fs pulses of 1.56 µm light from a mode-locked ultrafast laser inscribed Er-doped waveguide laser. Passive mode-locking was achieved using a carbon nanotube saturable absorber.
Dynamic nonlinear absorption of composite-type single-wall carbon nanotube saturable absorbers is characterized using both femtosecond and picosecond pump pulses. Results are compared with numerical simulations based on two commonly used saturable absorber models.
