Directly measured squeeze factors over GHz bandwidth from monolithic ppKTP resonators
Benedict Tohermes, Sophie Verclas, Roman Schnabel
Squeezed vacuum states of light with bandwidths in the gigahertz range are required for ultrafast quantum sensors, for high-bandwidth QKD and for optical quantum computers. Here we…

Laser Scanning Microscopy for Tomographic Imaging of Roughness and Point Absorbers in Optical Surfaces
Leif Albers, Malte Hagemann, Roman Schnabel
High-precision laser interferometric instruments require optical surfaces with a close to perfect contour, as well as low scattering and absorption. Especially point absorbers are…
