Light Scattering from Contamination and Defects - Measurement, Analysis, and Modelling [PDF]

open access: yesEPJ Web of Conferences, 2022
Light scattering induced by contamination and defects on optical components can quickly limit the component’s performance. Therefore, imperfection analysis and budgeting are mandatory - but also challenging tasks.

Ansatz from Non-Linear Optics Applied to Trapped Bose-Einstein Condensates [PDF]

open access: yes, 2007
A simple analytical ansatz, which has been used to describe the intensity profile of the similariton laser (a laser with self-similar propagation of ultrashort pulses), is used as a variational wave function to solve the Gross-Pitaevskii equation for a ...
