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
The results of experimental studies of spectral, temporal, and spatial self-seed lasing characteristics at the wavelength of 391 nm in pure nitrogen at different values of specific pump power are presented. Pumping was carried out by a femtosecond radiation pulse at the wavelength of 950 nm. The possibility of obtaining lasing pulse duration close to transform-limited (1.83 ps) is presented. It is shown that far-field radiation divergence decreases with increasing lens focal length, and it correlates well with the geometric dimensions of laser plasma. © 2023 Optica Publishing Group
