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
We theoretically propose a new form of laser beam, named the finite-energy Airy–Lorentz–Gaussian (ALG) beam, which can be decomposed into an exponentially modified Airy function in the x direction and a Lorentz–Gaussian function in the y direction. Based on the Huygens diffraction integral formula, an analytical propagation expression for the finite-energy ALG beam passing through a paraxial ABCD optical system has been derived. For special cases, the propagation properties of the finite-energy ALG beam through the free space, a thin lens, and a fractional Fourier transformation (FrFT) system are studied numerically and graphically. Our results provide an effective and alternative way to describe the finite-energy non-diffracting light beams.
