Laser Colloquium - 141422
The laser colloquium consists of a weekly event, where renowned speakers from academia and industry will present an advanced introduction to their research areas. The goal is to get acquainted with various hot topics around laser technology.
Mid-IR and Terahertz Photonics -141425
The lecture starts with a description of the major approaches for mid-infrared (wavelengths of 2-20µm) light generation including fundamentals for each technique. The techniques covered are ion-doped solid-state lasers, fiber lasers, semiconductor lasers, and laser sources based on nonlinear optical frequency conversion. Then we review a range of applications: spectral recognition of molecules and trace gas sensing, biomedical and military applications, high-field physics and attoscience. In the second part of the lecture, longer wavelengths in the so-called Terahertz domain (wavelengths from 20µm up to millimeters) are discussed following a similar structure to the above.
Master-Project Optics Fundamentals (LAP PO 2024) -142270
The students receive information material about the fundamental work flow in optical laboratories and data analysis in Python. In three experiments the gained knowledge of the students is tested and futhermore applied to two optical setups and some data.
The practical experiments are the alignment of a single mode fiber coupling setup and a Michelson interferometer. In the Python experiment data interpolation and Fourier transform are in the focus of the exercise.
Ultrafast Laser Physics and Technology -141424
The lecture starts with the fundamentals how to mathematically describe an electromagnetic pulse in the time- and frequency domains, and continues to describe how linear and nonlinear effects, as well as different technologically relevant combinations of effects affect them. Afterwards, different methods to measure and characterize pulses and pulse trains aswell as generation of ultrashort pulses are discussed.
