Vol. 63 Jens Herrmann, Attosecond Transient Absorption Spectroscopy: Controlling Extreme Ultraviolet Light-Matter Interaction 1st edition 2015. XVIII, 154 pages, € 64,00. ISBN 978-3-86628-526-2 |
Attosecond transient
absorption spectroscopy is still a relatively young discipline of attosecond science. Even though femtosecond transient
absorption spectroscopy is a well-known and established experimental technique,
it required the creation of coherent XUV bursts of attosecond
duration with higher-order harmonic generation (HHG) to extend the technique
into the attosecond regime. As an all optical technique, it is based on
the cross-correlation of pulsed XUV radiation with femtosecond infrared (IR)
pulses in the sample under investigation and the subsequent detection of the
transmitted radiation. Its high temporal resolution allows to
explore electron dynamics on their natural time scale.
In this work, we examine the optical properties of He in the XUV spectral range in different experiments and
with the help of numerical simulations. Moreover, we present attosecond solid-state transient absorption spectroscopy in
a polycrystalline diamond membrane. Our experimental data reveal the fully
reversible modification and control of the optical transmission of
polycrystalline diamond in the XUV spectral range with the help of the
femtosecond IR pulse.
About the author:
Jens Herrmann received
his diploma in physics in 2010 from Philipps-Universität
Marburg working on semiconductor disk lasers. He joined the Institute of
Quantum Electronics at ETH Zurich in the same year. He focused in his research
on the investigation of ultrafast processes in atoms and solid-state systems
with the help of attosecond transient absorption
spectroscopy.
Keywords: Attosecond
transient absorption spectroscopy, attosecond science,
