High-flux capillary based XUV source via the direct engineering of a laser induced ionization profile
High-flux capillary based XUV source via the direct engineering of a laser induced ionization profile
High harmonic generation (HHG) has proven to be a fascinating and incredibly useful nonlinear optical phenomenon and has led to the realization of tabletop sources of coherent extreme ultraviolet (XUV) radiation. Capillary based geometries in particular have attracted a great deal of attention due to the lengthy regions over which HHG can occur and the potential to phase match the HHG process leading to a large increase in XUV flux [1]. Until now reabsorption of XUV radiation has been a major problem when designing high-flux sources, in both capillary and other geometries. In this work we have used computational modelling to optimize our original capillary design in an effort to minimize the absorption of the generated XUV. Subsequent experimental work has shown a flux increase of almost 50 times over our existing capillary-based source, regardless of the maximum gas pressure.

Abstract
High harmonic generation (HHG) has proven to be a fascinating and incredibly useful nonlinear optical phenomenon and has led to the realization of tabletop sources of coherent extreme ultraviolet (XUV) radiation. Capillary based geometries in particular have attracted a great deal of attention due to the lengthy regions over which HHG can occur and the potential to phase match the HHG process leading to a large increase in XUV flux [1]. Until now reabsorption of XUV radiation has been a major problem when designing high-flux sources, in both capillary and other geometries. In this work we have used computational modelling to optimize our original capillary design in an effort to minimize the absorption of the generated XUV. Subsequent experimental work has shown a flux increase of almost 50 times over our existing capillary-based source, regardless of the maximum gas pressure.
