Abstract Due to the unique properties of two-dimensional (2D) materials, much attention has been paid exploration and application 2D materials. In this review, we focus on materials in mode-locked fiber lasers. We summarize synthesis methods for integration with based saturable absorbers. discuss performance diverse lasers typical operating wavelength such as 1, 1.5, 2 3 μm. Finally, a summary outlook further applications new are presented.
It is essential to detect nitrogen dioxide (NO2) in the air, which hazardous human health, with accuracy and convenience. According our prior findings, ZnO responds quickly to...
Abstract In this article, a high-quality saturable absorber (SA) based on two-dimensional ternary chalcogenide Ta 2 NiS 5 nanosheet has been successfully fabricated and used in 1- 1.5-μm spectral regions to generate ultrafast laser pulses. The -based SA is by mechanical exfoliation sandwiched between two fiber ferrules form fiber-compatible SA. On the basis of twin-detector technique, nonlinear optical absorption -SA characterized 64.7% 11.95% modulation depths with 1.3 0.72 MW/cm saturation...
We report Q-switched and mode-locked erbium-doped all-fiber lasers using ternary ReS2(1−x)Se2x as saturable absorbers (SAs). The modulation depth intensity of the film SA are 1.8% 0.046 MW/cm2. In mechanism output, pulse was centered at 1531.1 nm with maximum energy minimum width 28.29 nJ 1.07 μs, respectively. operation, 1561.15 nm 888 fs, repetition rate 2.95 MHz, 0.275 nJ. To best our knowledge, this is first on Er3+-doped fiber laser transition metal dichalcogenides. This work suggests...
We investigated the ternary ReS<sub>2(1−x)</sub>Se<sub>2x</sub> alloys and fabricated few-layer ReS<sub>1.02</sub>Se<sub>0.98</sub> nanoflakes to realize passive Q-switch noise-like pulses operating at 1 μm wavelength.
Metal–organic frameworks (MOFs) are a new kind of microporous materials whose unique properties make them promising as coatings for solid phase microextraction (SPME). However, previous MOF SPME exclusively focus on single-linker MOFs, and the selective enrichment polar or nonpolar targets depends polarity linker surface which greatly limits application coating in real samples. Here, we report hybrid MOF-coated stainless steel fiber biomarkers exhaled breath from gastric cancer patients....
In this paper, we demonstrate excellent ultrafast optical performance of ternary transition metal dichalcogenide ReS1.02Se0.98 saturable absorber with high power tolerance and large modulation depth in thulium-doped fiber laser. Q-switching tunable repetition frequency pulse duration, mode-locking energy were generated our experiment. The average output power/pulse energy/pulse duration the mode-locked train 313 mW/13.6 nJ/1.43 ps, respectively.
