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.

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.

Numerical Photonics in Python - 141482

The goal is to use the Py­thon pro­gramming lan­gua­ge to solve com­mon every-day tasks that arise in Pho­to­nics. Sol­ving pro­blems using pro­gramming is the main focus of the lec­tu­re and all tasks will re­qui­re it.
