Abstract:
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.
Biography:
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.
