The Leibniz-Institut für Kristallzüchtung (IKZ) is a leading research institution in the area of science & technology as well as service & transfer of crystalline materials. Our goal is to enable solutions for urgent societal challenges (e.g. communication, artificial intelligence, climate protection, health etc.) by modern electronic & photonic technologies. The work covers the full spectrum from basic over applied research up to pre-industrial development and is performed in collaboration with national and international partners from university, academy and industry. The institute is part of Forschungsverbund Berlin ( and a member of the Leibniz Association You can find more details on the institute webpage: 

We are offering a 

PhD Student Position (m/f/d)

for the topic:

Growth and characterization of fluoride crystals for nonlinear optics in the UV spectral range


The key responsibilities of the PhD student will include:

  • Growing highly UV-transparent BaMgF4 crystals.
  • Characterizing grown crystals through, e.g., transmission spectroscopy, laser scattering tomography, and determination of nonlinear optical coefficients.
  • Conducing laser frequency doubling experiments.
  • Collaborating with the research team to design and implement new experimental setups.
  • Analyzing and interpreting results, and contributing to scientific publications and conferences.
  • Keeping up-to-date with the research on nonlinear optical materials for the vacuum UV and related areas.

The applicant must have:

  • A master’s degree (or equivalent) and strong knowledge in solid-state physics, optics, laser physics, materials science or a closely related field.
  • Research experience, preferably in optical characterization and material synthesis.
  • Excellent analytical, problem-solving, and communication skills.
  • Ability to work independently as well as collaboratively in a team-oriented environment.
  • Motivation and passion for scientific research.
