The **Leibniz-Institut für Kristallzüchtung (IKZ)** is one of the leading institutions in the field of growth of crystalline solids. These play a fundamental role in photovoltaics, micro-, opto
We are currently looking for a
**Master student (M/F/d)**
for the topic:
**“Laser cooling of solids in the 2-µm spectral range”**
**The aim of this master program is to study laser cooling of thulium (Tm)
- and holmium (Ho)-doped fluoride crystals.** These materials, known as laser crystals for the 2-µm spectra range, potentially provide laser cooling efficiencies twice higher than Yb-doped materials excited at 1 µm. Despite the potential of laser cooling at 2 µm spectral range, this topic has not yet been investigated in detail owing to the lack of powerful, wavelength tunable, and relatively narrowband sources around 2 µm.
This master thesis involves the following tasks:
- Growth of high-quality fluoride single crystals doped with Tm and/or Ho ions (at IKZ)
- Spectroscopic characterization of the grown crystals for a wide range of temperatures (at IKZ)
- Laser cooling characterization using laser sources emitting in the 2-µm spectral range (at ISL)
