Metric Options: Counts1 Year3 YearSelecting 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
In this study, we experimentally demonstrated the fabrication of a passively Q-switched Nd:YAG laser using a hybrid organic-inorganic methylammonium lead halide (CHNHPbI) perovskite as a saturable absorber (SA). The broadband linear transmittance in the 0.3-1.1 μm range and the nonlinear optical absorption at 1064 nm were measured. The CHNHPbI SA exhibited large nonlinear saturable absorption with a modulation depth and saturation intensity equal to 3.9% and 6.5 MW cm, respectively. Using the CHNHPbI SA, a stable Q-switched laser operation with a maximum average output power of 388 mW corresponding to a pulse width of 192 ns was achieved. Thus, the CHNHPbI film is an efficient SA candidate for stable lasers and has great potential as a broadband nonlinear optical material for ultrafast photonics.
