Focusing and Wavefront Splitting of an Extreme Ultraviolet Laser with a Tubular Optical Element

open access: yesPhotonics, 2023
A capillary discharge extreme ultraviolet laser is focused and wavefront split at 46.9 nm by a tubular optical element. The reflectivity at 46.9 nm is both simulated and measured to be higher than 90% with a slight optical aberration.

Focusing on the Focusing Illusion... [PDF]

open access: yesSSRN Electronic Journal, 2013
The paper presents evidence that validate the focusing illusion. Specifically, the forecasted impact of a basketball championship on students’ subjective well-being was exaggerated because of their intense focus on the event. However, the self-reported states of being for life domains not closely associated with the focal event remained stable ...
