Abstract

In this talk, mid-infrared ultrafast lasers from 2μm to 3.5μm based on two-dimension materials will be introduced. With grapheme-gold film saturable absorber mirror, femtosecond mode-locking was realized at 2μm and 2.4μm. Furthermore, with bandgap-controllable black phosphorus saturable absorber, mode-locked pulses was achieved at 2.8μm and 3.5μm in Er:ZBLAN fiber laser, and 3.5μm is the longest wavelength for mode-locked lasers so far.
