A 2.7 $\mu$m Backward Wave Optical Parametric Oscillator Source for CO$_2$ Spectroscopy

Autor: Vågberg, Adrian, Brunzell, Martin, Widarsson, Max, Mutter, Patrick, Zukauskas, Andrius, Laurell, Fredrik, Pasiskevicius, Valdas

In this study, we demonstrated the direct use of an inherently narrowband backward wave in the mid-infrared for CO$_2$ and H$_2$O vapor spectroscopy in ambient air. This wave is generated in a backward wave optical parametric oscillator (BWOPO) pumpe

Backward wave optical parametric oscillation in a waveguide

Autor: Mutter, Patrick, Laurell, Fredrik, Pasiskevicius, Valdas, Zukauskas, Andrius

A backward wave optical parametric oscillator (BWOPO) waveguide in periodically poled Rb-doped KTP is presented. The waveguide exhibits low loss (0.16 dB/cm) and has an oscillation threshold, almost 20 times lower than the corresponding bulk device.
