Spectrally resolved far-fields of terahertz quantum cascade lasers
Martin Brandstetter, Sebastian Schönhuber, Michael Krall +6
We demonstrate a convenient and fast method to measure the spectrally resolved far-fields of multimode terahertz quantum cascade lasers by combining a microbolometer focal plane ar…
Random Lasers for Broadband Directional Emission
Sebastian Schönhuber, Martin Brandstetter, Thomas Hisch +7
Broadband coherent light sources are becoming increasingly important for sensing and spectroscopic applications, especially in the mid-infrared and terahertz (THz) spectral regions…
Reversing the Pump-Dependence of a Laser at an Exceptional Point
M. Brandstetter, M. Liertzer, C. Deutsch +6
When two resonant modes in a system with gain or loss coalesce in both their resonance position and their width, a so-called "Exceptional Point" occurs which acts as a source of no…
