When it comes to ultrafast lasers, Margaret Murnane’s name is one of the best known for her work in this field of science. Since 1999, she has been a professor at the University of Colorado’s NSF-funded JILA Physics Frontier Center, where she and her husband Henry Kapteyn pioneer research in ultrafast x-ray science. Additionally, the two also own a small laser company. Margaret is credited with building one of the fastest lasers ever, operating in matters of merely femtoseconds. After a lecture at the National Science Foundation on ultra-fast lasers and their applications for nano- and materials research, Ivy Kupec from the NSF sat down with this well-published scientist who originates from County Limerick, Ireland to talk further about these uber speedy lasers, science and even Archimedes.
