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
The causes and suppression methods of parasitic lasing in transverse direction of Fe 2+ :ZnSe laser are analyzed theoretically and experimentally. For a crystal with given diameter, there exists a maximum pump spot diameter d max, below which the parasitic lasing doesn’t occur. The effective maximum pump spot diameter d max can be increased by coating graphite on the side of the laser crystal, and the average increase of d max is about 1.7 times after coating. The thermoelastic stresses and deformations on the Fe 2+ :ZnSe crystal under pulsed pumping mode are modeled, with results showing that it is possible by choosing doping profile shape to significantly reduce optical distortions and increase pulse power.
