In the past two decades, great progress has been made in the development of inexpensive,
compact and efficient mid-infrared pulsed fiber laser Q-switched, mode-locked, and gain …

As a rising star of transition metal oxides (TMOs), cuprous oxide (Cu2O) has a relatively
narrow direct bandgap and features strong light–matter interaction, large optical absorption …

Two-dimensional transition metal dichalcogenides (TMDs) have been widely used in
ultrafast optics. However, the traditional TMDs such as MoS 2 and WS 2 have narrow …

Two dimensional (2D) ternary chalcogenides, a significant class of optoelectronic materials,
exhibit distinctive structures and possess exceptional physical and chemical properties. In …

Herein, we report nanostructures of NiTe and NiTe2 nanorods (NRs) with stoichiometric
chemical compositions grown in an efficient one-pot hydrothermal approach. In the …

A stable mid-infrared saturable absorber with a high damage threshold is urgently required
for high-performance optical modulation in the mid-infrared regime. Here, we demonstrate …

Passively mode-locked fiber lasers have applications in industry, optical communication,
biology, chemistry and so on. Saturable absorber (SA) is a key component in mode-locked …

Two-dimensional transition-metal dichalcogenides, specifically MTe2 (M= V and Ta), have
recently inspired significant interest due to their unique electronic properties. However, their …

We demonstrated the generation of nanosecond mid-infrared (MIR) pulse from an Er 3+-
doped ZrF 4-BaF 2-LaF 3-AlF 3-NaF (ZBLAN) fiber laser modulated by platinum ditelluride …

We have demonstrated the stable Q-switched Er-doped fluoride fiber laser with the help of
the few-layered Ta 2 NiS 5 in the mid-infrared spectral range. We fabricated the mid-infrared …
