Numerical Study on the Potential Enhancement of Organic Terahertz Sources through Tilted Pulse Front Pumping

open access: yesAdvanced Photonics Research, EarlyView.
In this article, two individually successful concepts, the tilted pulse‐front pumping technique and organic terahertz crystals for highly efficient THz generation are combined in the framework of numeric calculations resulting in increased conversion efficiency, increased damage threshold, and extended lifespan for ≈2 μm pumping.

Waldorfpedagogiken – religion eller inte?

open access: yes, 2014
Waldorfpedagogiken har utvecklats från antroposofin och används idag i skolor över hela världen. Antroposofin uppfyller flera av de viktigaste kriterierna i de vanligaste definitionerna av religion.  I denna artikel behandlas frågan om huruvida waldorfpedagogiken ska uppfattas som religiös eller inte.

Stimulated Raman Scattering with Optical Vortex Beams

open access: yesAdvanced Photonics Research, EarlyView.
This study presents exact analytical expressions for stimulated Raman scattering with Laguerre‐Gaussian beams, revealing signal dependence on topological and hyperbolic momentum. The results provide a theoretical foundation for coherent Raman imaging and detecting orbital angular momentum of light via structured light in nonlinear optics.
