The mid-infrared (MIR) represents a large portion of the electromagnetic spectrum that is
progressively being exploited for an enormous number of applications. Thermal imaging …

Lasers based on erbium ions using 4 I 11/2​→​ 4 I 13/2 transition can generate laser
radiation in the spectral range from 2.7​ μm to 3​ μm. Since the strong absorption peak of …

In this paper, we report 4 different saturable absorbers based on 4 transition metal
dichalcogenides (MoS_2, MoSe_2, WS_2, WSe_2) and utilize them to Q-switch a ring-cavity …

In our work, passively mode-locked and Q-switched Er-doped fiber lasers (EDFLs) based on
titanium disulfide (TiS2) as a saturable absorber (SA) were generated successfully. Stable …

Chip-scale, high-energy optical pulse generation is becoming increasingly important as
integrated optics expands into space and medical applications where miniaturization is …

We demonstrate a 2.8 μm gas Raman laser in a methane-filled hollow-core negative-
curvature fiber with average power of 113 mW, pulse energy of 113 μJ and estimated peak …

Efficient diode-pumped passively Q-switched Er: Lu_2O_3 laser operation at 2.84 μm was
realized. A few-layer MoS_2 nanosheet film on a YAG substrate, was fabricated and …

Enormous performance gains have been made in fluoride-based fiber lasers operating
around 3 μm due to advances in fiber fabrication and improvements in high-power pump …

We demonstrated a Q-switched fiber laser based on Tungsten Disulfide (WS_2) saturable
absorber. The WS_2 nano-sheets were prepared by liquid phase exfoliation method and the …

A diode-pumped, actively Q-switched 2.8? μm fiber laser oscillator with an average output
power of more than 12? W has been realized through the use of a 35? μm core erbium …
