Two-dimensional materials are widely used in a variety of fields, such as medical treatment,
industrial preparation, machining, etc. In this review, we have made a detailed description of …

Compared with continuous wave lasers, ultrafast lasers have the advantages of ultra-short
pulse width and ultra-high peak power, and have significant applications in optical …

Here, we investigated the nonlinear optical (NLO) characteristics of carboxyl-functionalized
graphene oxide (GO-COOH) in the near-infrared (NIR) region. The results revealed that GO …

We present high mode-locking performances from an erbium-doped fiber laser (EDFL) by
using graphene oxide (GO) and reduced graphene oxide (r-GO) as saturable absorbers …

For the first time, we report a femtosecond mode-locked Erbium-doped fiber laser (EDFL) by
using mechanically exfoliated graphite deposited onto a D-shaped optical fiber. The …

In this work, we report a femtosecond mode-locking Erbium-doped fiber laser using
mechanically exfoliated rhenium disulfide (ReS_2) deposited onto the polished surface of a …

A kind of saturable absorber (SA) based on layered MoSe 2 nanosheets has been
fabricated successfully by an ultrasound-assisted liquid phase exfoliation method. The as …

A compact multi-wavelength harmonic passive mode-locked (MWHML) erbium-doped fiber
laser (EDFL) has been demonstrated by integrating a Barium Titanate (BaTiO 3) in the ring …

In this thesis, we investigate experimentally the generation of high energy nanosecond
tunable square pulses and high output power ultrashort pulses in fiber lasers. First, since …
