Toward integrated tantalum pentoxide optical parametric oscillators
Maximilian Timmerkamp, Niklas M. Lüpken, Shqiprim Adrian Abazi +3
We present a hybrid waveguide-fiber optical parametric oscillator (OPO) exploiting degenerate four-wave mixing in tantalum pentoxide. The OPO, pumped with ultrashort pulses at 1.55…

Multi-color stimulated Raman scattering with a frame-to-frame wavelength-tunable fiber-based light source
Thomas Würthwein, Kristin Wallmeier, Maximilian Brinkmann +4
We present multi-color imaging by stimulated Raman scattering (SRS) enabled by an ultrafast fiber-based light source with integrated amplitude modulation and frame-to-frame wavelen…

Supercontinuum generation in media with sign-alternated dispersion
Haider Zia, Niklas M. Lüpken, Tim Hellwig +2
When an ultrafast optical pulse with high intensity is propagating through transparent material a supercontinuum can be coherently generated by self-phase modulation, which is esse…
