Seminar:  "Supercontinuum mid-IR sources", Peter Moselund

Peter M. Moselund
NKT Photonics

This presentation will briefly cover the basics processes involved in supercontinuum generation before going on to focus on mid-IR supercontinuum. The benefits of various soft glasses will be considered and we will present the work done at NKT Photonics where we have developed a mid-infrared supercontinuum source based on modelocked picosecond fiber lasers. The source is pumped by a ≈2 um laser based on a combination of erbium and thulium and use ZBLAN fibers to generate a 1.75-4.4 µm spectrum. We will present results obtained by applying the source for mid-infrared microscopywhere absorption spectra can be used to identify the chemical nature of different parts of a sample. Subsequently, we discuss the possible application of a mid-IR supercontinuum source in other areas including infrared countermeasures.

Dr. Peter M. Moselund is a Research Scientist at NKT Photonics, which is the leading manufacturer of visible supercontinuum sources. He received a PhD from The Technical University of Denmark in 2009 for his work on long pulse supercontinuum generation in photonics crystal fibers. He has worked for six years with pulsed fiber lasers for supercontinuum generation and during the last two years he has been leading the mid-IR supercontinuum generation activities at NKT Photonics.
