In this talk, I will present recent work from our group on the spectral extension of various fibre-based sources into both the visible and mid-infrared. We typically use a combination of fibre (χ3)…
Ferrimagnets (FiM) embody an intriguing magnetic order in between ferromagnets (FM) and anti-ferromagnets (AF). Common FM materials exhibit a single exchange interaction (J) favoring parallel…
The recent development of tabletop soft x-ray sources based on high harmonic generation (HHG) has made systematic experiments on ultrafast soft x-ray absorption spectroscopy more accessible [1]. This…
