Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Saturable absorbers (SAs) are key devices for passive Q-switching. All-inorganic halide perovskites demonstrate superior stability compared to their organic-inorganic hybrid counterparts, making them more promising candidates as SAs. A high-quality, all-inorganic halide perovskite CsPbBr 3, designed for mid-infrared (MIR) broadband saturable absorption, has been successfully fabricated. The saturable absorption properties of this material within the MIR region have been thoroughly characterized. Characterization outcomes reveal that CsPbBr 3 possesses outstanding broadband saturable absorption characteristics. For the first time, passive Q-switching operation has been successfully achieved in the MIR region, specifically at wavelengths of 1.9 μm and 2.8 μm, utilizing the CsPbBr 3 SA. Peak powers of 5.57 W at the 1.9 μm wavelength and 5.23 W at the 2.8 μm wavelength were achieved. The experimental results indicate that CsPbBr 3 is an efficient SA material, holding significant promise for the development of pulsed lasers with broad bandwidth and high energy outputs.
