Summary
A femtosecond Mmd-IR optical parametric amplifier source for waveguide nonlinear optics. The mid-infrared is an immensely important region of the optical spectrum for sensing toxic or illicit molecules or pollutants using their spectral fingerprints. The equipment will facilitate the development of new techniques for sensing based on nonlinear processes in waveguides.
