Extreme ultraviolet optical constants

In the vacuum ultraviolet and extreme ultraviolet (EUV), the indices of refraction of all materials become complex: N = n + ik , or N = 1- d + ik … more

Frequency Comb Spectroscopy

We use frequency combs based on ultrafast mode-locked lasers to perform precision spectroscopy in the near- and mid-infrared domains, for rapid, … more
