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
We report temporally shaped vortex phase laser pulses for two-photon excited fluorescence of dyes. The particularly tailored pulses are generated by first utilizing a temporal pulse shaper and subsequently a two-dimensional spatial pulse shaper. Various vortex phase shaped structures are demonstrated by combining different two-dimensional phase patterns. Moreover, perpendicular polarization components are used to achieve an enhanced radial two-photon excited fluorescence contrast by applying third order phase functions on the temporal pulse shaper. Particularly, the spatial fluorescence structure is modulated with a combination of Gaussian and vortex phase shaped pulses by modifying only the phase on the temporal modulator. Thereby, interference structures with high spatial resolution arise. The introduced method to generate temporally shaped vortex phase tailored pulses will provide new perspectives for biophotonic applications.
