Kort presentation
Jag är forskare på laser labbet HELIOS. Detta labb innehåller två laserkällor som genererar ultrakorta (< 40 fs) pulser av extrem ultraviolett strålning (mellan 20 till 70 eV) som används i en pump-prob uppställning för att studera ultrasnabba dynamiska processer i gas, vätskor och kondenserad materia. På senare tid har vi också utvecklat en THz-uppställning i labbet. Jag är främst intresserad av magnetodynamik och studier av ultrasnabba fenomen i magnetiska material.
