Leibniz-Institut für Kristallzüchtung (IKZ)
Berlin
The Leibniz Institute for Crystal Growth (IKZ) performs basic and applied research in the fields of
growth, characterization and processing of crystalline matter. It is part of Forschungsverbund
Berlin e. V. and a member of the Leibniz Association. The IKZ is a leading research institution in
the area of crystal growth of technologically important materials for micro-, opto- and power
electronics, sensors, optics and laser technology. This ranges from explorative fundamental
research to pre-industrial development.
IKZ invites applicants for a
PhD Position
(part-time)
available from January 1, 2018, on the topic:
„Growth and laser characterization of Er3+-doped sesquioxide crystals“
Cubic rare-earth sesquioxides such as Lu2O3, Y2O3, and Sc2O3 are excellent host materials for
lasers in the near and mid infrared spectral range. In particular when doped with Er3+ operated
at the 3 µm transition, these materials allowed for higher efficiencies and output power than any
other laser material. However, due to their high melting points the growth by crucible-based
techniques is difficult and expensive.
In this thesis, sesquioxide crystals shall be grown by the crucible-free optical floating zone
technique (OFZ). The growth experiments will be carried out using a new growth facility acquired
for this purpose. Moreover, the grown materials will be spectroscopically characterized with
respect to their application as laser crystals in the new labs of the Center for Laser Materials at
the IKZ. The most promising samples will be utilized for laser experiments in the wavelength
range around 3 µm.
Applicants must hold a Diploma or an MSc degree in physics, optical sciences, laser engineering
or related studies. Practical experiences in the fields of crystal growth or laser engineering are
desirable. The ability to work in a team and very good English skills are required, basic
knowledge in German language is desirable.
For scientific questions please contact Dr. Christian Kränkel, Tel.: +49 30 6392 3019, e-mail:
christian.kraenkel@ikz-berlin.de
The employment will be limited and paid according to the TVöD labor
agreement. Among equally qualified applicants, preference will be given to
disabled candidates. The IKZ is an equivalent opportunity employer and
actively supports reconciliation of work and family life.
We await your informative application with reference to the job number
10/17, including the usual documents, by November 1, 2017. Please send
them to Mrs. Ruthenberg: personal@ikz-berlin.de
