Carbon nanotubes (CNTs) possess remarkable nonlinear optical properties; a particular
application is to function as a mode locker used in ultrafast fiber lasers to produce ultrashort …

We report an ultrafast laser mode-locked with a graphene saturable absorber. The linear
dispersions of the Dirac electrons in graphene enable wideband tunability. We get∼ 1 ps …

Graphene and other two-dimensional (2d) crystals are promising materials for photonic and
optoelectronic applications. A key requirement for these applications is the development of …

Ultrafast lasers play an increasingly important role in many applications. Nanotubes and
graphene have emerged as promising novel saturable absorbers for passive mode-locking …

There is an increasing demand for all-fiber passively mode-locked lasers with pulse
repetition rates in the order of gigahertz for their potential applications in fields such as …

Optical frequency combs have revolutionized optical frequency metrology and are being
actively investigated in a number of applications outside of pure optical frequency metrology …

An Er-doped mode-locked fiber laser with a saturable absorber based on single mode-
graded index multimode-single mode fiber (SMF-GIMF-SMF) with inner micro-cavity is …

Waveform-stabilized laser pulses have revolutionized the exploration of the electronic
structure and dynamics of matter by serving as the technological basis for frequency-comb …

Saturated absorption spectroscopy reveals the narrowest features so far in molecular gas-
filled hollow-core photonic crystal fiber. The 48-68 μm core diameter of the kagome …
