Thin-disk laser pump schemes for large number of passes and moderate pump source quality
K. Schuhmann, T. W. Hänsch, K. Kirch +6
Novel thin-disk laser pump layouts are proposed yielding an increased number of passes for a given pump module size and pump source quality. These novel layouts result from a gener…
Thin-disk laser multi-pass amplifier
K. Schuhmann, M. A. Ahmed, T. Graf +8
In the context of the Lamb shift measurement in muonic helium we developed a thin-disk laser composed of a Q-switched oscillator and a multi-pass amplifier delivering pulses of 150…
Cavity-enhanced Raman Microscopy of Individual Carbon Nanotubes
Thomas Hümmer, Jonathan Noe, Matthias S. Hofmann +3
Raman spectroscopy reveals chemically specific information and provides label-free insight into the molecular world. However, the signals are intrinsically weak and call for enhanc…
Multipass laser cavity for efficient transverse illumination of an elongated volume
Jan Vogelsang, Marc Diepold, Aldo Antognini +11
A multipass laser cavity is presented which can be used to illuminate an elongated volume from a transverse direction. The illuminated volume can also have a very large transverse…
Frequency-agile dual-comb spectroscopy
Guy Millot, Stéphane Pitois, Ming Yan +4
We propose a new approach to near-infrared molecular spectroscopy, harnessing advanced concepts of optical telecommunications and supercontinuum photonics. We generate, without mod…
Transverse-mode coupling and diffraction loss in tunable Fabry-Pérot microcavities
Julia Benedikter, Thomas Hümmer, Matthias Mader +4
We report on measurements and modeling of the mode structure of tunable Fabry-Pérot optical microcavities with imperfect mirrors. We find that non-spherical mirror shape and finite…
